How every fact on this site was checked
139 facts. Each one is in our own words, each one has a source, and each one was checked against that source on 10 November 2026.
How we check
We read each source and wrote each fact in our own words. Our build stores the text of every source page, and for each fact it checks that the key words and figures, the “checks” in the table, really appear on the source page. If any check fails, the site does not build. Where good sources disagree, we show each version in a “Sources differ” box rather than picking one. Anything that is our own reading, rather than a sourced fact, is labelled Our opinion.
Known disagreements
- Keel laid. Late winter 1626 (Vasa Museum timeline) or 1625 (Vrak).
- How many ships were ordered. Four (Vasa Museum timeline) or Vasa “and two other ships” (US Naval Institute, 1969).
- Who finished the ship. Hein Jakobsson, Hybertsson’s assistant (Vasa Museum timeline), and Margareta Nilsdotter, his widow (Vasa Museum exhibition).
- Length. 69 m (Vasa Museum timeline) or 47 m, with a width of 11.5 m (Vrak). Neither says what it measures.
- Aboard and dead. All but 30 survived (Vasa Museum); about 30 dead of 150 to 250 aboard (Vrak); an estimated 134 sailors and a guessed 50 drowned (US Naval Institute, 1969).
- Bolts replaced, 2011–2018. More than 5,000 (preservation timeline) or 4,000 (main timeline), both Vasa Museum.
- Weight. Over 1,200 t fitted out (timeline), about 900 t around 2000 (preservation timeline), 800 to 1,200 t today, exact weight unknown (facts page).
- Museum architects. Marianne Dahlbäck and Göran Månsson (museum page) or Hidemark Månsson Arkitektkontor AB (timeline).
- How long she sailed. About 20 minutes (Vasa Museum facts page; PRI, 2016); both agree on the distance, about 1,300 m.
What we left out
- Some Vasa Museum pages we tried could not be read, and an encyclopedia page would not load fully; none of them is cited.
- One source page says the guns on the upper decks made the centre of gravity “low”, in the same sentence as saying they helped capsize the ship, and calls Vasa a 16th-century ship although she was built in the 1620s. We did not use those lines.
- We give no exact weight for the ship today: the museum says it is unknown.

| 17 | In January 1625 the king signed a contract with the Dutch master shipwright Henrik Hybertsson and his business partner Arendt de Groote to build four new ships. Vasa was to be the most powerful warship in the Baltic. | Vasa Museum: Timeline | 3 passed |
| 18 | A 1969 US Naval Institute article says the king ordered Vasa ‘and two other ships’ in January 1625. | US Naval Institute Proceedings: The two voyages of the Wasa (March 1969) | 1 passed |
| 19 | Vasa’s keel was laid in late winter 1626 at Skeppsgården, the navy yard in Stockholm. | Vasa Museum: Timeline | 1 passed |
| 20 | Vrak, the Museum of Wrecks, gives the keel-laying as 1625. | Vrak, Museum of Wrecks (Stockholm): Vasa | 1 passed |
| 21 | Hybertsson was already ill when work started. By the summer of 1626 he could no longer supervise, and his assistant Hein Jakobsson took over the ship; Hybertsson died barely a year later. | Vasa Museum: Timeline | 2 passed |
| 22 | The museum’s exhibition says Margareta Nilsdotter, Hybertsson’s widow, led the building of Vasa after he died in the spring of 1627. | Vasa Museum: His Majesty’s Ship (exhibition) | 1 passed |
| 23 | The navy yard was on Skeppsholmen, today the peninsula called Blasieholmen, then an island reached by a guarded wooden bridge. | Vasa Museum: The Ship Yard | 2 passed |
| 24 | In the warm months over 400 people worked at the yard. About half were year-round staff recruited in Sweden; the rest were seasonal workers, mostly from the Netherlands and Germany, paid about twice as much. | Vasa Museum: The Ship Yard | 4 passed |
| 25 | The two groups spoke different languages, trained in different traditions and used different systems of measurement. | Vasa Museum: The Ship Yard | 2 passed |
| 26 | Timber came from estates south and west of Stockholm, sawn planks from Riga and Amsterdam, tar from southern Sweden and Finland, hemp from Latvia, coal from England and sailcloth from the Netherlands and France. | Vasa Museum: The Ship Yard | 3 passed |
| 27 | Vasa was launched in the spring of 1627, and hundreds of craftsmen spent the summer finishing the hull and rigging. | Vasa Museum: Timeline | 1 passed |
| 28 | She carried 64 cannon on her maiden voyage, but eight gunports were empty: the yard could build a ship faster than the royal foundry could cast guns. | Vasa Museum: Vasa, the machine of war | 2 passed |
| 29 | The main armament was 48 bronze 24-pounders, each firing a ten-kilogram ball, with eight 3-pounders and six short guns for close-range work on the upper deck. | Vasa Museum: Vasa, the machine of war | 3 passed |
| 30 | One side’s guns could fire 250 kilograms of shot at once: about four times a typical Swedish warship of the 1620s, and twice the largest ships of other northern European navies. | Vasa Museum: Vasa, the machine of war | 2 passed |
| 31 | Vrak says the 48 big guns weighed about 1,200 kilograms each. | Vrak, Museum of Wrecks (Stockholm): Vasa | 1 passed |
| 32 | The king, a keen artillerist, wanted big, heavily gunned ships for artillery duels; most similar orders were cancelled after he died, because the navy did not want such ships. | Vasa Museum: Vasa, the machine of war | 2 passed |
| 33 | There were over 700 sculptures and decorations on the ship, meant to show that Gustav II Adolf was the rightful king with God on his side. | Vasa Museum: The Sculptures of Vasa | 2 passed |
| 34 | The figurehead is a three-metre lion holding the Vasa coat of arms, with twenty Roman emperors along the beakhead behind it. | Vasa Museum: The Sculptures of Vasa | 2 passed |
| 35 | From the toilets in the beakhead, the crew looked at two carved Polish noblemen: Sweden’s enemy, shown humbled. | Vasa Museum: The Sculptures of Vasa | 1 passed |
| 36 | From 1990 to 2002 Peter Tångeberg analysed about 1,200 paint samples. Vasa was bright: strong colours and gold leaf on the sculptures, much of the ship painted red, the rest tarred red-brown. | Vasa Museum: The Sculptures of Vasa | 5 passed |
| 37 | Mårten Redtmer, a German master sculptor, carved several of the most important figures, with the Dutchman Johan Thesson and the German Hans Clausink. | Vasa Museum: The Sculptures of Vasa | 2 passed |
| 38 | The navy’s plan for 1628 was 133 sailors and 300 soldiers; the soldiers would only board for battle service and were not aboard when she sank. | Vasa Museum: Life on Board | 2 passed |
| 39 | With soldiers aboard, about 450 men would have shared less than 600 square metres of living space. | Vasa Museum: Life on Board | 1 passed |
| 40 | Before she sailed, captain Söfring Hansson had 30 men run back and forth across the deck while Vice Admiral Klas Fleming watched. The ship rolled so much that the test was stopped for fear she would capsize at the quay. | Vasa Museum: The Inquest | 2 passed |
| 41 | Fleming was overheard to say ‘If only His Majesty were at home!’, but he did not report it, and the king was pressing for the ship to go to sea. | Vasa Museum: The Inquest | 2 passed |
| 42 | 10 August 1628 was a Sunday. Crew families were allowed aboard for the first leg; guests, including women and children, were to get off at the Vaxholm fortress. | Vasa Museum: The Disaster | 3 passed |
| 43 | She was bound for the fleet base at Älvsnabben in the Stockholm archipelago, to be flagship of the reserve squadron. Two companies of soldiers, 300 men, were to board there. | Vasa Museum: The Disaster | 3 passed |
| 44 | She cast off from below the palace between four and five in the afternoon. With the wind from the south she was warped along the waterfront to what is now Slussen, then four of her ten sails were set and a salute was fired. | Vasa Museum: The Disaster | 4 passed |
| 45 | Under the cliffs of Södermalm there was little wind. A small gust made her heel and slowly recover; at the gap in the cliffs at Tegelviken a stronger gust pushed her so far over that water poured in through the open lower gunports. | Vasa Museum: The Disaster | 3 passed |
| 46 | Within minutes she was on the bottom, 32 metres down, with her masts sticking out of the water. Some people held on to the masts, some were picked up by small boats, and some swam the 120 metres to Beckholmen. | Vasa Museum: The Disaster | 3 passed |
| 47 | All but 30 of the crew and guests survived, the Vasa Museum says. Most of the dead were trapped inside the ship. | Vasa Museum: The Disaster | 2 passed |
| 48 | Among the dead was Captain Hans Jonsson, the ship’s first-named captain, still aboard because a second experienced captain often sailed on a new ship’s first trip. | Vasa Museum: The Disaster | 2 passed |
| 49 | Vrak says between 150 and 250 men and women were aboard, and about 30 people died. | Vrak, Museum of Wrecks (Stockholm): Vasa | 2 passed |
| 50 | The 1969 US Naval Institute article estimated 134 sailors aboard and guessed that 50 drowned. | US Naval Institute Proceedings: The two voyages of the Wasa (March 1969) | 1 passed |
| 51 | Skeletons from at least 17 people were found during the excavation of the 1960s, and more remains were found by divers in 1966. | Vasa Museum: Skeletons from Vasa | 2 passed |
| 52 | Of the roughly thirty who died, only one is named in the historical sources: Captain Hans Jonsson. | Vasa Museum: Skeletons from Vasa | 2 passed |
| 53 | New DNA work in 2023 showed that one skeleton thought to be a man was a woman. | Vasa Museum: Skeletons from Vasa | 2 passed |
| 54 | Thousands of Stockholm’s people watched, along with several foreign ambassadors. | Vasa Museum: Timeline | 1 passed |
| 55 | Captain Söfring Hansson was imprisoned and questioned ‘before his clothes were even dry’. He swore the crew had been sober and the guns properly lashed. | Vasa Museum: The Inquest | 2 passed |
| 56 | The king was not in Stockholm: he was with the army in Prussia, at war with Poland-Lithuania. The council’s first report went to him on 12 August, and his reply demanded that the guilty be punished. | Vasa Museum: The Inquest | 2 passed |
| 57 | An inquest of 17 councillors and naval officers, chaired by the king’s older half-brother Admiral Karl Karlsson Gyllenhielm, met on 5 September 1628 at the Tre Kronor palace. | Vasa Museum: The Inquest | 3 passed |
| 58 | The ship’s master, Jöran Matsson, had stowed the ballast, 120 tons of stone, and said the ship was ballasted as deep as it should be. | Vasa Museum: The Inquest | 2 passed |
| 59 | The builders said Vasa was built to Hybertsson’s design, which the king had approved. Hein Jakobsson added that he had widened the ship by around 40 centimetres. | Vasa Museum: The Inquest | 2 passed |
| 60 | In the end nobody was officially blamed or punished, and everyone questioned was eventually promoted. | Vasa Museum: The Inquest | 1 passed |
| 61 | An appendix records the opinion of expert captains and shipwrights: the ship did not have enough ‘belly’ to carry its high, heavy upperworks. | Vasa Museum: The Inquest | 1 passed |
| 62 | The museum calls the hearing, to a degree, ‘a piece of political theatre’: blame had to fall somewhere without embarrassing the king. | Vasa Museum: The Inquest | 1 passed |
| 63 | The 1969 article says no plans or models were used in building the ship, and the king had personally approved its main dimensions. | US Naval Institute Proceedings: The two voyages of the Wasa (March 1969) | 2 passed |
| 64 | Within three days an English engineer, Ian Bulmer, was allowed to try to raise Vasa. He got her upright on her keel but could not lift her. | US Naval Institute Proceedings: The two voyages of the Wasa (March 1969) | 2 passed |
| 65 | In 1663–1665, 35 years after the sinking, divers led by Albrecht von Treileben and Andreas Peckell used a diving bell to bring up almost all of the cannon, which were sold abroad. | Vasa Museum: Timeline | 3 passed |
| 66 | In 1920 two brothers asked permission to blow up wrecks in the harbour, including Vasa, for black oak to make Art Deco furniture. The authorities said no. | Vasa Museum: Timeline | 3 passed |
| 67 | Hybertsson was an experienced, respected shipwright, but Vasa was new to him in size and armament, and there was no way to calculate a ship’s performance in advance: the mathematics was more than a century away. | Vasa Museum: The Disaster | 2 passed |
| 68 | New warships were often unstable at first (‘tender’ or ‘crank’) and there were accepted fixes: change the guns, add planking at the waterline, or take off a deck. Vasa was so crank that she did not survive long enough to be fixed. | Vasa Museum: The Disaster | 3 passed |
| 69 | The upperworks were too tall and heavy for the small amount of hull below the waterline. That might have made her fast, but it put the centre of gravity too high, so even a light breeze could heel her alarmingly. | Vasa Museum: The Disaster | 2 passed |
| 70 | The museum calls leaving the gunports open ‘a fateful decision’: closed, they would have kept the water out, and the ship might have survived long enough to be rebuilt. | Vasa Museum: The Disaster | 2 passed |
| 71 | Fred Hocker, an archaeologist at the Vasa Museum, measured every piece of wood in the ship and found it lopsided, more so than most ships of the time: there is more structure on the port side than the starboard. | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 5 passed |
| 72 | Hocker says that without ballast the ship would probably heel to port, the side she went over on. | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 1 passed |
| 73 | Four of the workmen’s rulers were found: two in Swedish feet of twelve inches and two in Amsterdam feet of eleven inches. | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 2 passed |
| 74 | A broken fragment of a rule, lost during building in 1626–1627, was found behind a hull plank removed in 2010. Both kinds of rule are found on Vasa, ‘but no two are the same length’. | Vasa Museum: Find in focus, fragment of a carpenter’s rule | 3 passed |
| 75 | Radio Sweden, citing the news agency TT, put a Dutch foot at 281 mm and a Swedish foot at 297 mm. | Sveriges Radio (Radio Sweden): Vasa ship was “lopsided” | 2 passed |
| 76 | Radio Sweden reported that the researchers do not think the uneven shape made Vasa sink, though it could have made her slightly less stable; the gunports, for example, are not in matching places on the two sides. | Sveriges Radio (Radio Sweden): Vasa ship was “lopsided” | 3 passed |
| 77 | The museum’s 2012 survey measured the whole ship digitally at more than 80,000 points, and found it leans more than had been thought. There were no drawings to build from. | Vasa Museum press release: Så snett är skeppet Vasa (June 2012, in Swedish) | 3 passed |
| 78 | Hocker found the deck structure heavier than it needed to be for Vasa’s guns, probably because Hybertsson, who had never built a two-gundeck ship, erred on the side of caution. | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 3 passed |
| 79 | Some historians blamed the king for changing the ship’s dimensions after building began, but Hocker’s measurements found no evidence for that. | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 2 passed |
| 80 | In Hocker’s words, ‘the design was simply flawed from the beginning.’ | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 1 passed |
| 81 | PRI’s 2016 report says two strong gusts hit the ship about twenty minutes into the voyage. | GBH News / PRI’s The World: New clues emerge in centuries-old Swedish shipwreck (October 2016) | 1 passed |
| 82 | Hein Jakobsson worked at the yard until 1638, building a string of large, successful ships; Söfring Hansson became supervising officer of the navy yard. | Vasa Museum: The Inquest | 2 passed |
| 83 | In the early 1950s Anders Franzén, a fuel engineer in the navy and an amateur archaeologist, started searching for the navy’s lost ships, with Vasa near the top of his list. | Vasa Museum: The Search for Vasa | 2 passed |
| 84 | The 1969 article says the most important reason the wreck survived was the absence of the wood-eating shipworm, Teredo navalis, in the Baltic’s low-salt water. | US Naval Institute Proceedings: The two voyages of the Wasa (March 1969) | 1 passed |
| 85 | The museum says the wood survived well because the ship was new and sank in cold, dark, almost oxygen-free water; only the outer few centimetres were degraded by bacteria. | Vasa Museum: Timeline for the preservation of Vasa | 2 passed |
| 86 | Dragging the south side of the channel, he found ‘rusty iron stoves and ladies’ bicycles, Christmas trees, dead cats’, and realised he was looking in the wrong place. | Vasa Museum: The Search for Vasa | 2 passed |
| 87 | A 1955 survey for a planned bridge showed a lump 50 metres long and six metres high off the Gustav V dry dock on Beckholmen. The navy diver Per Edvin Fälting knew it was not blasting rubble. | Vasa Museum: The Search for Vasa | 2 passed |
| 88 | On 25 August 1956 Franzén’s home-made coring device brought up black oak; 20 metres further on, it did it again. | Vasa Museum: The Search for Vasa | 2 passed |
| 89 | In early September Fälting went down and felt his way along a wooden wall with two rows of square openings: an old warship with two gundecks. | Vasa Museum: The Search for Vasa | 2 passed |
| 90 | The museum says it is ‘a little misleading’ to call the wreck lost: it was on a 19th-century chart, divers visited it in the 1840s and 1860s, and the navy dive school trained on it. | Vasa Museum: The Search for Vasa | 4 passed |
| 91 | Franzén’s big contribution was the idea that the ship could be raised and made the centrepiece of a museum, and the skill to persuade people to do it. | Vasa Museum: The Search for Vasa | 1 passed |
| 92 | The Neptune Company, part of Broströms, Scandinavia’s biggest salvage firm, did the lift and agreed not to charge for it. | Vasa Museum: The Salvage | 2 passed |
| 93 | Ideas such as filling the hull with ping-pong balls, or freezing it in a giant ice cube, were quickly dropped; the salvors would only use a proven method. | Vasa Museum: The Salvage | 1 passed |
| 94 | From 1957 to 1959 navy divers dug six tunnels under the ship and pulled steel cables through them to two pontoons, Oden and Frigg. | Vasa Museum: The Salvage | 2 passed |
| 95 | The pontoons were flooded almost full, the cables tightened, then the water pumped out, so the ship rose with them. | Vasa Museum: The Salvage | 1 passed |
| 96 | When a cannon was raised on 5 September 1958, Swedish Radio covered it live. | Vasa Museum: The Salvage | 1 passed |
| 97 | The first lift was on 20 August 1959. Each lift gained a little under a metre, and in 18 stages the ship was moved to 17 metres deep near Kastellholmen. | Vasa Museum: The Salvage | 3 passed |
| 98 | For more than 18 months divers plugged bolt holes, covered the gunports and rebuilt the bow and stern to make the hull watertight. | Vasa Museum: The Salvage | 1 passed |
| 99 | At 09.03 on 24 April 1961 the first eroded frames broke the surface, then four carved warriors’ heads. Swedish Television broadcast it live to all of Europe. | Vasa Museum: The Salvage | 3 passed |
| 100 | The 1969 article gives the cable as some 4,500 feet of 6-inch steel wire, and says the first move took 28 days. | US Naval Institute Proceedings: The two voyages of the Wasa (March 1969) | 2 passed |
| 101 | On 4 May 1961 Vasa was towed to the Gustav V dry dock on Beckholmen and floated on her own keel onto a concrete pontoon. | Vasa Museum: The Excavation | 2 passed |
| 102 | Archaeologists led by Per Lundström worked aboard for five months in a constant muddy drizzle, because the ship was sprayed with water day and night. | Vasa Museum: The Excavation | 3 passed |
| 103 | Finds went into water tanks to wait for conservation. There were not enough, so the project bought up old bathtubs from Stockholm’s scrap merchants. | Vasa Museum: The Excavation | 1 passed |
| 104 | In those five months the team recovered more than 30,000 objects. | Vasa Museum: The Excavation | 1 passed |
| 105 | Over 4,000 coins were found, all small change, in chests and in the pockets of clothes worn by eleven skeletons on the decks. | Vasa Museum: The Excavation | 2 passed |
| 106 | Six of Vasa’s sails were found folded in a locker, still tied up as they had come from the sailmaker in 1627. | Vasa Museum: The Excavation | 2 passed |
| 107 | From 1963 to 1967 divers searched ‘the Pit’ where she had lain, recovering many sculptures, the beakhead, upper sterncastle, anchors and the longboat, nearly 12 metres long with a smaller boat inside. | Vasa Museum: The Excavation | 3 passed |
| 108 | To stop the waterlogged wood shrinking and cracking as it dried, the hull was sprayed with polyethylene glycol (PEG), a water-soluble wax, from April 1962 to January 1979. | Vasa Museum: Conservation | 2 passed |
| 109 | At first spraying was done by hand: five men took five hours to cover the ship. An automatic system with 500 nozzles followed in 1965. | Vasa Museum: Conservation | 2 passed |
| 110 | After 17 years of spraying came another nine years of slow air-drying. | Vasa Museum: Conservation | 1 passed |
| 111 | PEG is also found in cosmetics such as lipsticks and face creams. | Vasa Museum: Conservation | 1 passed |
| 112 | The sails were so fragile they could not carry their own weight. Conservators backed them with fibreglass fabric, a job that took over a decade; the museum holds the remains of 650 square metres of sail. | Vasa Museum: Conservation | 3 passed |
| 113 | Almost all the 5,000 iron fastenings corroded on the seabed, and sulphur from the polluted harbour water got into the wood. | Vasa Museum: Timeline for the preservation of Vasa | 1 passed |
| 114 | In the rainy summer of 2000, crowds of wet visitors sent the humidity swinging, and yellow and white acidic spots appeared on the ship. | Vasa Museum: Timeline | 2 passed |
| 115 | A new climate system in 2004 keeps the hall at 53 ± 2 per cent humidity and 18.5 ± 1.5 °C. | Vasa Museum: Timeline for the preservation of Vasa | 1 passed |
| 116 | Replacing the rusty 1960s bolts took seven years and was finished in 2018: more than 5,000 bolts, saving about 8 tonnes. The museum expects the new ones to last at least 150 years. | Vasa Museum: Timeline for the preservation of Vasa | 3 passed |
| 117 | The museum’s main timeline puts it at 4,000 bolts and says the ship is ‘now eight tons lighter’. | Vasa Museum: Timeline | 2 passed |
| 118 | In 2014 researchers test-fired an exact copy of one of Vasa’s guns over 50 times. Its range was over 1,000 metres, but real fighting range was probably under 500, and every shot went through up to 80 cm of oak. | Vasa Museum: Timeline | 4 passed |
| 119 | From 1961 until 1988 Vasa lived in a temporary home, the Wasavarvet museum. | Vasa Museum: The Museum | 1 passed |
| 120 | The temporary museum opened on 16 February 1962 with a salute from two of Vasa’s cannon; 439,300 people bought tickets that year. | Vasa Museum: Timeline | 3 passed |
| 121 | A Nordic architecture competition in 1981 drew 384 designs. The museum’s page on the building names the winners as Marianne Dahlbäck and Göran Månsson, with their design ‘Ask’. | Vasa Museum: The Museum | 2 passed |
