Hesperange Castle probably dates from the early 13th century when the Counts of Luxembourg gave Hesperange to the Lords of Rodenmacher who sided with the French when the Burgundians conquored Luxembourg in 1443. Maximilian of Austria dismantled the castle in 1480 and 1482 after battles with Gerard of Rodenmacher. In 1492, he transferred it to the Lords of Baden who had to pawn it in 1692 and could only reclaim it in 1740.
After the French captured the castle in 1796, the French government nationalized it and sold it by auction in 1798. Later parts of the ruins were sold individually and by 1820 seven houses stood on the castle grounds. Now a national monument, the ruins are still privately owned.
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.
