Travelers visit Roskilde, Denmark to explore its Viking past, but few know about its secrets that lay hidden beneath the fjord. Nearly 1,000 years ago, the people of Roskilde deliberately sank Viking ships to block the entrance to Roskilde Fjord and protect the city from attack. Rediscovered between 1957 and 1962, the five vessels revealed new insights into Viking seafaring and strategy. See the ships up close at the Viking Ship Museum in Roskilde, just outside of Copenhagen, on a Holland America shore excursion, curated with The History Channel™.
