Wechterswinkel Abbey, dedicated to the Holy Trinity and Saint Margaret, was founded in 1134 or 1135 by Embricho of House of Leiningen, bishop of Würzburg, and King Conrad III of Germany.
It was so severely damaged in the wars of the 16th century that it was unable to continue, and was dissolved in 1592 by Julius Echter von Mespelbrunn, the then bishop of Würzburg. The assets realised were invested to endow parish benefices and schools.
The church, a Romanesque basilica heavily altered in the early 19th century, has survived as the village parish church, now dedicated to Saints Cosmas and Damian.
Some of the monastic buildings also survive, put to secular uses, but have been comprehensively altered and retain no medieval character.
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.
