Located 30 km (20 miles) west of Denmark’s current capital, Copenhagen, is one of the country’s early capitals, Roskilde. One of Denmark’s oldest cities, it is where many monarchs are buried. Their royal tombs can be found at the 12th century Roskilde Cathedral, the first brick Gothic cathedral in Scandinavia. Another key attraction is the Viking Ship Museum, which contains the remains of five Viking ships that were sunk to protect Roskilde from sea invaders. Other sights you might want to see include the royal palace, now an art gallery, and the Roskilde Jars, three mammoth vases that commemorate the city’ 1,000th anniversary. In late June, early July a giant rock music event called the Roskilde Festival takes place here.
