The Château de Ramstein is built on the same crest as the Château de l'Ortenbourg. Standing at an altitude of 384 m, it is dominated by the Château de l'Ortenbourg from which it is separated by a few hundred metres.
It was built around 1293 as a rear base during the siege of Château de l'Ortenbourg by Otto von Ochenstein, during the conflict between Adolf of Nassau and Albert of Habsburg. Originally built as a simple tower to support a siege engine, it grew at the start of the 14th century into a true castle with the strengthening of the tower and an extra wall. In 1421, it was attacked and pillaged by Strasbourg. It was destroyed in 1633 by the Swedes during the Thirty Years' War. At the start of the 19th century it became the property of baron Mathieu de Fabvier, who also owned Ortenbourg. Today, all that remains are the exterior wall and two turrets, built of granite.
Because of the risk of landslides, the castle has been closed to visitors since 1983. The castle has been listed as monument historique by the French Ministry of Culture since 1924. It is the property of the commune.
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.
