Sospel Cathedral formerly the seat of the schismatic Bishopric of Sospel, created in 1378. Apart from a belltower of either the 11th or the 13th century, from the Lombard period of Sospel's history, the cathedral was built between 1642 and 1762, and is claimed to be the largest building in the Alpes-Maritimes. The Renaissance façade is from 1642, and contains in two niches the statues of the town's protectors, Saint Hippolytus and Saint Absende. Inside, the principal feature is the altarpiece in carved wood in three panels, containing the figure of the 'Immaculate Virgin of Sospel'. It is by the artist François Brea, of a family of artists from Nice, from the 15th or early 16th century.
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.
