The town of Airvault is dominated by the castle Château d'Airvault built on a hill. In the Middle Ages, this strategic position made it an important part of the powerful defensive system of the town.
The castle was constructed on an earlier Gallic oppidum in the 11-15th centuries. It was besieged and conquered in 1207 by Philip II of France. On 3 October 1569, after the Battle of Moncontour which saw the victory of the Duke of Anjou (the future Henri III), Gaspard de Coligny who commanded the defeated Calvinists the burning of the castle in revenge for René Ysoré (son of Jean Ysoré) who contributed to his defeat. Burned, the castle was abandoned by its owners.
At the start of the 20th century, the owner constructed a house in the lower court and planned to destroy the castle to sell the materials.
The Château d'Airvault is considered as one of the rare remaining specimens of military architecture of the 11th century. From this time, there remains the enceinte with its two uncrowned towers and its keep whose well-preserved silhouette marks the urban landscape.
The 14th- and 15th-century buildings inside the enceinte replaced in the original buildings. Two quadrangular towers added obliquely to the corners of the enceinte on the ramparts are dated to the 13th or 14th century. The rectangular châtelet, defended by a bretèche and hoardings, is pierced by a door with a portcullis and murder hole giving access to the court.
The main dwelling of the 15th century is located along the west curtain wall. Among the outbuildings are the prison with its two vaulted cells lit by an arrowslit and a stable.
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.
