Brunegg castle was built on a hill at the edge of the Jura mountains in the 13th century. This castle was probably built, together with near Wildegg castle, as part of the Habsburg border defenses. The castle was occupied by Habsburg knights, including Schenken von Brunegg and Gessler von Meienberg. In 1415 the castle was besieged by Bernese troops, but they lifted siege after a counterattack. However, Bern conquered the Aargau, and awarded the fief to the Segenser or Segesser family.
Between 1538-1798, the castle was subordinate to the Governor of Lenzburg. In 1815 it became the property of the Hünerwadel family of Lenzburg. The current owners of the castle, the von Salis family, inherited the castle through marriage from the Hünerwadels. For hundreds of years, the castle was poorly maintained, and in the 17th Century it was heavily damaged twice through storm and tempest. In 1805-06, the keep and out buildings were repaired and the roof was rebuilt.
The village of Brunegg owes its name and existence to the castle. Initially it belonged to the personal land of the Habsburgs. In the 14th Century, they granted the rights to low justice into the hands of the castle owners. Bern placed in the court of Othmarsingen in the Lenzburg district. In the 19th century it was part of the Brugg district though since 1840 it has been in the Lenzburg district.
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.
