Blatnica castle was built in the 13th century to protect a major trade route running from Nitra to the north. Soon afterwards it became a royal castle but the kings lost their interest in the castle's development after a new route, through Mošovce and Martin was built. The new owners of Blatnica Castle, the Révay family (from 1540), were more generous and the castle was significantly extended in the second half of the 16th century. The last reconstruction dated from 1744. Since 1790 the castle has been abandoned and has turned into ruins.
The castle is built on typo low ridge of Plešovica which separates the Turiec Basin from the Greater Fatra Range. It is freely accessible from the village of Blatnica by a marked footpath. The castle remnants are hidden in a forest with limited views at the Gader Valley, which stretches underneath, and the opposite Tlstá Mountain.
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.
