Built in the 14th century, Erdut Castle lies on a bluff 70 metres above the Danube. The surrounding area below the bluff is completely flat, which provided an excellent view of any marauding hordes invading from the east. The settlement and castle is first mentioned as Ardud in 1335. The documents of the 15th century in Titel provost and the Bánffy family owned estate is mentioned in the Erdődy, dated 1552 and 1687 between the Turkish occupations.
The castle was damaged in July 1991, during the Croatian War of Independence, in an artillery attack launched by the Yugoslav People's Army (JNA). In the aftermath of the attack, Croatian authorities sent a list of Croatia's cultural monuments marked with the protective sign of the Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict to the Yugoslav Defence Ministry and all JNA headquarters.
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.
