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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
