Earliest records of the Brzeg castle's existence describe a small fortress with a moat and fortified walls, built in 1235 during the reign of Henry I the Bearded. A square tower known as 'The Tower of Lions' was built adjoining the castle. The Piast family branch, which ruled over Duchy of Brzeg, lived in the castle between 1311 until 1675. In 1342, the castle was made the capital seat of the duchy after which it was refurbished many times. In 1370, Prince Ludwik I extended the castle and constructed its chapel which includes the Piast dynasty mausoleum.
During Frederick II of Legnica's reign in 1544, more buildings were added to the castle, with the construction completed in 1560. The additions were in the form of two new buildings, a large courtyard enclosing the buildings and an ambulatory. Additional structures built during this period included a tower gate which was the entrance to the structure. Busts of the Piast princes were part of the gate's decor. Modifications in design were from the Gothic style fort to the Renaissance type of architecture in Silesia.
In 1741, the castle was destroyed by the Prussian forces in the First Silesian War, during which the ruins were used as a warehouse for the Prussian Army. After the war, the town with most of Silesia was annexed from Austria to Prussia. Brieg remained in Prusso-German possession until most of Silesia was transferred to Poland in 1945.
During a fire in 1801, there was further damage to the castle. In 1920, reconstruction of the abandoned castle began, but during World War II, damage to the castle was quite extensive. The castle was rebuilt in Renaissance style during 1966–78 and again from 1980–94. It currently serves as the Museum of the Silesian Piasts.
The rebuilt castle is also called 'The Silesian Wawel'. It was rebuilt by Jakub Parr, Franciscus Pahr, and Bernard Niuron from Italy. Its present facade is known as one of the finest Renaissance period structures in Central Europe. The courtyard has been restored with triple story galleries. The interior of some rooms in the eastern wing, which are in the Renaissance style on the ground floor, are well preserved.
The museum, which is part of the castle, has exhibits which trace the history of the Silesian Piasts. Some of the notable paintings exhibited are from a collection of the National Museum of Wrocław and paintings of Michael Leopold Wilmann, a well known Silesian Baroque painter. The museum also has well-preserved sarcophaguses of the dukes of Legnica and Brzeg.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
