Viking Ship Museum Roskilde

One of the most important shipwreck sites is found in the silt of Roskilde Fjord, which is only a meter deep in places. In particular, the remains of numerous dragon boats (longships) from the Viking Age came to light here. In 1962, 5 Viking ships were found, in 1996, when there had long been a museum for the ship finds and this was being expanded, nine more ships were discovered, one of which is 36 m long and thus the longest dragon boat find ever.

The museum may not look very attractive from the outside, but it is definitely worth a visit.
I have also visited this museum on previous visits to Roskilde.

The Viking Ship Museum in Roskilde has an active and vivid boatyard and you can join a sea voyage in a Viking ship.vikingeskibsmuseet.dk
