Reinhardstein Castle is located in valley of the Warche, in the village of Ovifat in the municipality of Waimes (Weismes). It was built in 1354 for Wenceslaus of Luxembourg, while still Count, by his vassal Reinhard of Weismes.
In 1550 following the marriage of Anne Naussau to Guillaume of Metternich, Reinhardstein became the property of this important Rhineland family, until the French Revolution. Abandoned, it fell progressively into important ruin.
In the 19th century it was nearly destroyed by quarrying, and since 1969 has been reconstructed.
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.
