The Château de Beaulon is a privately owned château located in Saint Dizant du Gua. The gardens, and landscape park, a Monument historique, are open to the public.
The château was built circa 1480 as a residence for the Bishops of Bordeaux. The château has both stone Gothic and Renaissance style facades. It is presently owned by the royal family of Abu Dhabi.
The present gardens were created beginning in 1942. The park includes a French formal garden around the château, and an English landscape garden. The garden is listed by the Committee of Parks and Gardens of the French Ministry of Culture as one of the Remarkable Gardens of France.
A major feature of the landscape park are the Fontaines Bleues, natural springs whose waters are an unusual brilliant hue of blue. There is also a round dovecote structure with a conical roof, dating from 1740, with fifteen hundred nesting holes.
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.
