The construction of Roskilde Cathedral began in 1170 and was completed 110 years later. However, the final appearance of the church was not formed at this time, as its interior and exterior were repeatedly changed. Roskilde Cathedral is famous not only for its architecture, but also for the fact that it served as a burial place for many Danish kings. The last royal couple buried here were King Frederick IX (1947) and his wife Ingrid of Sweden (1972).

There is one notable episode in the historiography of the Danish Vikings: in 1070, five ships were deliberately sunk near the city of Roskilde in order to block the path of enemy ships. Almost 900 years later, in 1962, all five were found and raised to the surface. Today, they form the basis of the exhibition of the Viking Ship Museum. There are also more recent finds, as well as many reconstructed ships, on which you can even now go for prey to coastal villages.
