Lillö Castle was built in in the 14th century among the natural defences offered by the inaccessible marshlands and the River Helge å. The first known owner was Åke Axelsson (Tott) in 1343. The castle belonged to Tott, Trolle and Huitfeldt families until it was destroyed in 1658–59. Today, displays inside the castle based on the finds made during various archaeological digs reflect life here in days gone by. Display panels in the courtyard provide information on the castle and its surroundings. A key is available from the Naturum Vattenriket visitor centre to gain admission to the castle.
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.
