In the 13th century, the Lords of Wiltz built a fortified castle on a rocky promontory, initiating the development of the upper town of Wiltz. In 1388, the French attacked the town and burnt the castle down but it was soon repaired. In 1453, Wiltz was again attacked, this time by the troops of Philip of Burgundy. The round Witches' Tower to the east of the gardens is the oldest part of today's castle. Under Count John VI of Wiltz, the construction of today's Renaissiance style castle was begun in 1631. After delays caused by the Thirty Years War, the main building was not completed until about 1720. The old chapel was finished in 1722 and the monumental staircase leading down to the gardens was completed in 1727. The castle premises were acquired by the State of Luxembourg in 1951 for use as an old people's home.
Since 1953, Wiltz Castle has been the venue of an international music festival attracting artists and orchestras of international repute. Since 1999, the castle's stables have housed the National Museum of Brewing. The museum traces the history of beer production over the past 6,000 years, especially more recent developments in Luxembourg. The little tanning museum (Musée de la Tannerie) presents the history of the leather industry in Wiltz which dates from 1644.
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.
