Follow in the footsteps of Viking warriors on a fascinating half-day adventure that takes you to Roskilde, visit two of its top attractions. It's a 60-minute drive from port to this picturesque city and former capital of Denmark. Enter the Viking Ship Museum and peruse the remains of five, 1,000-year-old Viking longboats that were excavated from the bottom of Roskilde Fjord. Outside, discover Museum Island, a working boatyard that displays the area's maritime legacy, where master craftsmen can be found building replica Viking-age vessels. Continue to Roskilde Cathedral, a UNESCO World Heritage Site, one of Denmark's earliest brick Gothic cathedrals. The interior is befitting the final resting place of almost 40 members of the Danish monarchy. Walk the grounds, take in the pretty views of the fjord, then relax on your scenic ride back to port.
