Château de Sauveterre was constructed at the end of the 13th century by Edward I of England on one of the principal routes between Périgord and Agenais. During the Hundred Years' War, it became a centrepiece in the Anglo-French war of attrition. It was burned in 1789 during the French Revolution.
It was bought by the aviator Jean Mermoz in 1936, less than a year before his death. He had seen the castle from the air. After his death, the castle was abandoned and became the property of the commune until it was sold in the 1980s.
The castle in its entirety, as well as its grounds and moat, have been classified as historical monuments since 19 September 2003. It is privately owned.
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.
