Finding the Vasa cannons–VA joins the search



Senast uppdaterad:


When the Swedish warship Vasa capsized and sank in Stockholm harbour on her maiden voyage on 10 August 1628, there were 64 cannons on board. When she was salvaged in 1961, only three of these were found. What happened to the rest of the cannons? The general public will soon be invited to join the search as part of a new international project.

“The aim of the Vasa cannon project is to promote international collaboration and stimulate interest in Europe’s maritime and industrial history. By engaging the public in the search, we hope more people will discover how exciting historical research can be,” said Lisa Månsson, Director of the Vasa Museum.

After the Vasa’s fateful maiden voyage, an operation was carried out from 1663–1683 to recover most of her bronze cannons from the sea bottom. According to historical records, the cannons were most likely sold to Great Britain, the Netherlands and Denmark. Only three remaining cannons were found when the Vasa was salvaged in 1961. Ever since the Vasa has been a treasure trove for anyone interested in learning more about the 17th century . But one mystery remains:

“What happened to the cannons? Were they ever used or were they melted down and turned into new objects? Have any of the cannons been preserved anywhere in the world? If so, where are they and how did they get there? These are the questions we hope this project will help us to answer,” said Fred Hocker, Director of Research at the Vasa Museum.

A three-stage investigation

The project consists of three parts. The first started in 2018 with an underwater survey of the bottom of Stockholm’s harbour to see whether any cannons remain on the seabed. In 2019, the second part consisted of archival research in Sweden, the UK, the Netherlands and Denmark to try to trace what happened to the cannons. The third part is a global citizen science project that is currently being planned.

“Volunteers from around the world will be working together with researchers to collect information about cannons. People will be encouraged to take photos of cannons that they come across in collections and exhibitions worldwide and upload them to a database, to discover whether they are the missing Vasa cannons,” said Fredrik Brounéus, a Researcher and Press Officer at VA.

An international collaboration

The project is led by The Friends of the Vasa Museum in conjunction with the Vasa Museum, Swedish National Maritime Museums and the British and Dutch embassies in Stockholm and the Swedish civil society organization VA (Public & Science). The Vasa is the world’s only preserved 17th century ship and the most visited maritime exhibit in the world.
