The Viking Ship Museum (Vikingeskibsmuseet) is the Danish national museum for ships, seafaring and boatbuilding in the prehistoric and medieval period.
Around the year 1070, five Viking ships were deliberately sunk at Skuldelev in Roskilde Fjord in order to block the most important fairway and to protect Roskilde from enemy attack from the sea. These ships, later known as the Skuldelev ships, were excavated in 1962. They turned out to be five different types of ships ranging from cargo ships to ships of war.
The Viking Ship Museum overlooks Roskilde Fjord and was built in 1969 especially to exhibit the five newly-discovered ships. In the late 1990s excavations for an expansion of the museum uncovered a further 9 ships including the longest Viking warship ever discovered, at 36 metres.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
