Useldange Castle stands on a small hill in the centre of the village overlooking the River Attert. The ruins present a reasonable picture of the medieval castle, especially the outer wall and one of the round towers. A bridge over the former moat, 10 metres wide, provides access to the castle. The keep, 25 metres tall, stands at the centre of the site.
The castle appears to date from the 12th century when the lordship of Useldange was created. One of the early lords was Théobald d'Useldange. After the dynasty died out in the middle of the 13th century, Jean de Rodemacher became the legitimate proprietor in 1415 by marriage with Irmgard de Boulay. In 1479, Maximilian I confiscated the property and charged Christopher of Baden with its upkeep. As a result of the war between France and Burgundy, the castle and its chapel were seriously damaged. William of Nassau-Vianden, who inherited the castle, sold it to François-Sébastien Bauer of Everlange in 1674. The castle fell increasingly into disrepair and the chapel was desroyed in 1903.
In 1924, American immigrant Mrs Kuhn-Wolff, originally from Useldange, returned to buy the ruined castle. After consolidating the walls in 1934, the family went on to build a modern property over the ruins of the castle's palace. It has now become the town hall. The castle is being restored by the State of Luxembourg.
The castle is open to visitors throughout the year. Special arrangements have been made to allow handicapped and weakly sighted visitors to experience the site.
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.
