The collegiate church of Saint-Mexme was the main religious building in Chinon up to the Revolution. It was originally built in the 5th century on the site of a monastery founded by Saint Mexme, a disciple of Saint Martin. The building was entirely rebuilt, enlarged and embellished between the 10th and 15th centuries, and became a major pilgrimage site. The building was deconsecrated following the Revolution and was left abandoned; in 1817 the transept bell tower collapsed, taking with it the east side of the building. The remaining parts (the west block and central nave) were converted into a school.
The school moved out at the beginning of the 1980s and major work was carried out to restore the original character of the building. Numerous fragments of wall paintings from the 11th to the 15th century were discovered. The church is only open for guided visits organized by the “Ville d’art et d’histoire” department.
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.
