Sandersdorf Castle is a 17th-century building on a medieval foundation. It stands on a spur of high land to the west of the village of Sandersdorf. The building has four wings. The east and south wings are decorated with bay windows and gables. The lower west wing contains the inner courtyard with open arcades. There are onion domes over the gatehouse and the castle chapel. The most valuable works of art are a crucifix by Ignaz Günther and the Romanesque tympanum on the outside.
A castle was built as the seat of the lords of Sandersdorf in the mid-12th century. The castle changed ownership several times in the 14th and 15th centuries. In 1420 it was burned by Duke Henry XVI of Bavaria-Landshut during his war with Duke Ludwig the Bearded of Bavaria-Ingolstadt. In 1425 Sandersdorf and its estate was awarded to the Muggenthal family. They held the castle for more than 200 years. The castle brewery was founded in 1550, and its Sandersdorf beer became widely known. The castle was destroyed during the Thirty Years' War (1618–1648), but the Muggenthals rebuilt it in its present form.
In 1646, soon after the reconstruction, Wolfgang Unverzagt Freiher von Roy purchased the property. He went bankrupt, and Johannes Jakob Lossius bought it in 1650. In 1675 it was inherited by his nephew Dominikus de Bassus, a professor at the University of Ingolstadt. During the War of the Spanish Succession (1701–1714) the building was devastated in 1703. Thomas Maria Baron de Bassus became a leader of the Illuminati in Italy, an secret society founded to promote enlightenment ideas such as opposition to superstition, prejudice, and abuse of state power. In 1787 the Bavarian police raised Sandersdorf castle and found compromising documents. His estate was temporarily confiscated. Baron de Bassus died in Sandersdorf in 1815.
Sandersdorf remained the property of the Barons de Bassus, and was partially restored in 1900 by the Munich architect Gabriel von Seidl. In 2008 the Wittelsbach Compensation Fund bought the castle and estate from the de Bassus family.
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.
