Château de Ballon is mentioned from the beginning of the 11th century. It is said to have been built by Robert I of Bellême to serve as a stronghold against the family of the Counts of Maine. The fortress quickly became the target of the Normans who sought to conquer the southern region.
From the 12th century onwards, Ballon passed into the hands of the Chaources family, who held the castle for two hundred years. The lordship was then under Anglo-Norman influence. In order to end the Plantagenet hegemony, Philip Augustus traveled to Maine. He captured Ballon twice in 1189 and 1199. The Ballon fortress was then burned and dismantled. Philip Augustus had it rebuilt and placed Hugues de Beauçais in charge.
During the Hundred Years' War, the fortress had to endure several sieges and was ravaged an conquered several times. The reconstruction of the keep and the part of Ballon began in 1469.
Today Château de Ballon is a triangle form castle with corner towers and moat. It has remarkable gardens built in the 1960s.
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.
