Aspelt Castle is a Baroque residence built in 1590 on the site of a medieval castle. The origins of Aspelt Castle date back to the 11th century when a fortified castle with a moat was built on the site, possibly on Roman ruins. The first written reference to the castle can be found in Theoderich von Wied's Echternach chronicles from 1132. The foundations of the round Gothic towers are probably from the 14th century while the current building was completed in 1590 following transformations carried out by the Ruelle, Kempt and Burthé families. In 1777, the Martinys extended the palace and installed new Baroque windows in the towers. In 1957, the ground floor of the south-west tower was restored.
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.
