The ruins of the medieval Šášov Castle stand above the river Hron. According to a legend, the lord of the Zvolen Castle had it built for his court joker who saved his life while hunting.
The task of the Šášov Castle was to guard the trade road and to collect toll. It became royal property in the 14th century and part of the dowry of the royal wives. In 1490 the family of Dóczy bought it from Queen Beatrix and reconstructed it into the Renaissance fort. The castle fell in decay after the Rebellion of Estates in 1708. Only some walls survive.
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.
