Château de Lauquerie is a former fortress built in the 14th century by the Templars, erected to defend the borders of the Dordogne and the village of Lauzun. It was offered by Henri IV to his squire Sire François de Longueval for having served him faithfully for 30 years. Remained for several decades in the Longueval family, it was partially destroyed during the French Revolution, then became the property of the Lajaunie family from 1889 to 1989. Completely renovated in the 90s, it is nowadays a private residence converted into tourist accommodation.
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.
