The Couvent des Jacobins was a monastery in Saint-Sever - Jacobin was the French term for the Dominican Order. Founded in 1280 thanks to the support of Eleanor of Castile, wife of Edward I of England, it was partly destroyed in 1569 by Huguenot troops under Gabriel, comte de Montgomery during the Wars of Religion.
It was partly rebuilt thanks to the support of père Antonin Cloche, a native of the town who became master-general of the order in 1686. Its cloister and south and west wings were restored in the Languedoc Romanesque style using pink brick and stone.
After the French Revolution it was re-used as a school, college, agricultural school, store, fire-station, municipal baths and finally a market. From the 1970s it has housed cultural aspects of the town, including the musée des Jacobins.
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.
