Sées Cathedral (Cathédrale Notre-Dame de Sées) dates from the 13th and 14th century and occupies the site of three earlier churches. The west front, which is disfigured by the buttresses projecting beyond it, has two stately spires of open work 230 ft. high. The nave was built towards the end of the 13th century. The choir, built soon afterwards, is remarkable for the lightness of its construction. In the choir are four bas-reliefs of great beauty representing scenes in the life of the Virgin Mary; and the altar is adorned with another depicting the removal of the relics of Saints Gervais and Protais. The church has constantly been the object of restoration and reconstruction. It has an organ by Claude Parisot.
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.
