Vikings, the great warriors of northern seas! Vikingeskibsmuseet (Vikings museum), located in the town of Roskilde, near Copenhagen (30 mins by car) houses several Viking ships, equipment and historical information. It's a cool outdoors and indoors experience. People running the museum even teamed up with their counterparts in Ireland and built a replica of a real viking ship and made a trip on it from Roskilde to Ireland. You can watch the documentary from that trip in the museum.
