Roskilde 6 is the longest Viking ship discovered, measuring about 36 metres.
The vessel was found in 1997 during work connected with the construction of the Viking Ship Museum’s hall in Roskilde, Denmark. It belonged to a group of ships uncovered in the area and was preserved only in fragments, but its surviving parts allowed researchers to reconstruct its exceptional length.
Roskilde 6 dates from around AD 1025, during the later Viking Age. Its size suggests that it was built for royal or elite use and could have carried a large crew. The ship’s design reflects the importance of naval power in the North Sea and Baltic regions.
Roskilde 6 is not the same as the Skuldelev ships, which were deliberately sunk in Roskilde Fjord to block navigation channels. The number identifies its place in the Roskilde excavation sequence, rather than a traditional historical name.
