The building time of Château du Hallier is not known precisely. It is recorded in the 15th century in deeds of sale. The castle was sold to Charles de l'Hospital in 1537. In the 18th century, the castle was used as a quarry; the square second floor disappeared. In the 19th century, the castle became a farm. One of the towers housed a potter's kiln until the early 20th century. Today castle is privately owned. It has been listed since 1967 as a monument historique by the French Ministry of Culture.
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.
