Hradisko Monastery was originally a Benedictine monastery, from the mid-12th century a premonstratensian monastery in Olomouc. It was established in 1078 and it serves as an military hospital since 1802.
The four-winged building with a rectangular platform, with corner towers and a moat, is divided by an inner lateral wing into two parts - the convent and the prelature. While the northern part of the monastery was built in the spirit of Italian Mannerism, the prelature building is High Baroque. The monumental front face of the prelature is adorned with sculptured architectural decoration and a portal with columns and a balcony. On the upper floor of the Prelature, there is a ceremonial hall. The leading Austrian painter Paul Troger contributed, along with others, to the inner decoration. Troger painted the monumental ceiling fresco on the theme of Christ’s Feeding of the 5000 in the year 1731. The fresco is surrounded by a painting of illusive architecture by Antonio Tassi. Equally significant is the painting and stucco decoration of the library’s vaults. The Italian painter Innocenzo Monti and the sculptor Baltassare Fontana worked together on it at the beginning of the 18th century.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
