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:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
