The Tihany Abbey is a Benedictine monastery established at Tihany in the Kingdom of Hungary in 1055 by King Andrew I of Hungary. Its patrons are the Virgin Mary and Saint Aignan of Orleans. King Andrew was buried in the church of the monastery in 1060. His tomb in the crypt of the church is only grave of a medieval King of Hungary which has been preserved until now. The church's ceiling is decorated with frescoes by Károly Lotz, depicting Faith, Hope and Love.
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.
