The Château de Guirbaden (or Girbaden) is a ruined castle in the commune of Mollkirch, Alsace. It is situated in the Guirbaden forest, near the village of Mollkirch on the left bank of the Magel River. The castle covers a larger area than any other in Alsace. Dating from the 11th century, over more than 500 years it suffered several attacks, destructions and reconstructions.
Out of the enclosure and the buildings, today only the main dwelling, the keep, sections of the surrounding wall and Saint Valentine’s Chapel remain. It offers a magnificent view of the Plain of Alsace and Bruche Valley.
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.
