The Château de Ramstein is a ruined castle in the commune of Baerenthal. This 13th-century castle was built by the lords of Falkenstein on the instructions of the bishop of Strasbourg to control the Zinselbach valley, probably in 1292. During the course of the 14th century, the lords of Ramstein transformed it into a den of brigands and it was destroyed in 1355 during a punitive expedition by the Strasbourgeois and their allies from Bern.
Below the castle can be seen two underground passages dug in 1936 by French military engineers as part of the Maginot Line. They were used as shelter by the local population during the battles of winter 1944-45. This site is currently closed to protect a colony of bats.
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.
