Budatín castle was built as a guarding castle in the second half of the 13th century near the confluence of the Kysuca and the Váh, where tolls were collected. At the beginning of the 14th century, originally royal fortress passed into the hands of Matthew III Csák and the castle, especially towers were fortified, and inside the fortress a new palace was built.
Since 1487, the new owner of the castle was Gašpar Suňog, whose family owned it until the end of the 18th century. At the half 16th century, the castle was rebuilt in the Renaissance style. The Turkish threat from the south, and more uprisings at the beginning of the 17th century forced Suňogs to fortify the castle in the Renaissance style. At that time, the Gothic castle was changed into comfortable Renaissance palace.
During the Baroque period in the 17th century, effort was concentrated on building a chapel and finishing various building of the castle and surrounding it by the park. After the Suňog family died, the new owners were the Csákys, who owned the castle until 1945. During the revolutions of 1848/1849, imperial troops seriously damaged the castle, which was repaired in 1870, and was serving as a barracks. The park's size was reduced by the construction of Košice-Bohumín Railway in 1872. The last major reconstruction was done in the 1922-1923, based on the historical and romantic motives. Today, the castle houses three exhibitions of the Považie museum.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
