The cog is the centrepiece of the museum. Behind the wreck, which is more than 600 years old, lies a research thriller: discovered by chance in 1962 in the mud of the Weser, the complex salvage took three years. Afterwards, a team of restorers assembled the 2000 individual parts. To prevent the brittle oak wood from shrinking, the wreck floated in a tank filled with preservative for 18 years; in 1999 the liquid was drained and the construction removed. The cog remains an exciting object of research for scientists from all over the world and is considered the best-preserved trading ship of the Middle Ages
