Château de Sainte-Suzanne was a property of the lords of Beaumont, viscounts of Maine, and was built in the 11th century. The most famous event of castle was when it succesfully repelled the conquer attempt of William the Conqueror in 1083-1086.
Installed on a rocky outcrop dominating the Erve valley, the Château de Sainte-Suzanne consists of a triangular courtyard made up of eleven round and square towers, a moat separating it from the medieval town or even a quadrangular keep with three levels near the drawbridge.
As for the dwelling, it reveals an architecture typical of the Henri IV period, at the transition between the Renaissance and the Classical, with a steep roof made of slates from Angers, a facade with bays or even pediments covering the skylights.
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.
