Sümeg Castle was built in the latter half of the 13th century by Béla IV of Hungary. It is situated atop a mountain called 'Castle Hill'. Later, it was presented as a gift to the Roman Catholic Archdiocese of Veszprém by Stephen V of Hungary. In the 15th century, the castle was fortified, and the second of two towers was built.In 1552, in response to the capture of Veszprém by the Turks, the castles was rebuilt and fortified to serve as a frontier fortress. In 1713, after the Austrian occupation during Rákóczi's War for Independence, troops set the castle on fire.
Today, the castle is the main tourist attraction for visitors to Sümeg. Since 1989, it has been privately held. It was restored on a large scale, and is now operated as a tourist attraction, providing events and tournaments. It is considered to be Hungary's most well-preserved fortress.
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.
