Église Saint-Georges de Châtenois is the Catholic parish church of Châtenois. The current church was built from 1759 until 1761 by the local architect Martin Dorgler, but retains a Romanesque steeple from the 12th century, crowned with a spire from 1525. It became a registered Monument historique in 1901.
The church houses some notable works of art, classified as Monument historique, among which are two 16th-century polychrome wooden Renaissance reliefs of the Nativity and the Assumption of Mary, and a 1765 pipe organ by Johann Andreas Silbermann.
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.
