The construction of Rietburg castle is dated to the period 1200 to 1204 and ascribed to the lords of Riet. These noblemen were initially vassals of the North Alsatian Benedictine abbey of Weißenburg, later they became ministeriales and feudatories of the then German Hohenstaufen lords.
In 1470, during the Weißenburg Feud between Prince-Elector Frederick the Victorious of the Palatinate and his cousin, Duke Louis the Black of Palatinate-Zweibrücken, the Rietburg was shelled by Leiningen troops and badly damaged, but remained inhabitable. The castle survived the Palatine Peasants' War of 1525 unscathed, but was finally destroyed during the Thirty Years' War (1618–48) and never rebuilt.
Since 1954, a chair lift, known as the Rietburgbahn has run from the Rhine Plain up to a terrace on the eastern side of the Rietburg. The return journey offers good views over the plain. The bottom station is accessible on foot or by car and is located near the schloss of Villa Ludwigshöhe, a stately residence built from 1846 to 1852 by order of Louis I of Bavaria.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.
