The Chateau de Caradeuc was built in 1722 by Anne-Raoul Caradeuc de la Chalotais. It is most famous by its gardens, built in the 19th century on the woodland hills of Bécherel in the formal French style. Gardens were designed in 1898 by Edouard André. Decorated with many statues the gardens offer a spectacular panorama over the high valley of the Rance. They are open on weekends and bank holidays in May, June and September.
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.
