Sainte-Foy church was built in the heart of Morlaas, the historic capital of Béarn. It has beautiful capitals carved in the choir, including the take-off of Sainte Foy, and the piton de Jaca, architectural motif finding themselves on the pilgrimage routes.The Romanesque portal, redesigned in the 19th century, has originals, visible in the exhibition hall of the Tourist Office. As for the remarkable original of the tympanum, it can be seen in the Chapel of Blessed Bernard. All 10 glass roofs were made by Mauméjean (1869).
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.
