The Château du Bernstein is a ruined castle in Dambach-la-Ville. It is among the oldest in Alsace. It was first mentioned at the beginning of the 11th century, though the northern surrounding wall can be dated to prehistoric times. The upper castle with keep, manor house and advanced works probably dates from the end of the 12th and early 13th centuries. In the Gothic era, the manor house was separated from the keep by a ditch, transformed later into a cistern. Towards the end of the 15th century, the St. Marguerite tower, so called from the name of the chapel there, was built in the rear courtyard.
Around 1835, Félix Dartein cleared the ground of the lower castle to build a house and some outbuildings which have disappeared.
Originally, the castle belonged to the Counts of Eguisheim Dabo. After the siege of 1227, it became the property of the bishop of Strasbourg and seat of the episcopal bailiffs until 1580.
The Château du Bernstein is state property and has been listed as a monument historique by the French Ministry of Culture since 1931.
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.
