Aywiers Abbey was founded in 1215 by Cistercian monks. It prospered and grew thanks to donations up to 2000 hectares. During the the French Revolution the abbey will be sold and the new owner demolished it partly. Today the seven-hectare garden is surrounded by ancient walls, containing superb hundred-year-old tree specimens, shrubs and rare plants, a pond and springs as well as a garden of aromatic and medicinal plant.
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.
