The Collégiale Saint-Thiébaut in Thann is one of the most ornate Gothic churches in the whole Upper Rhenish region.
The building was erected between 1332 (South lateral nave) and 1516 (achievement of the tower by master Rémy Faesch from Basel. It was damaged during World War II.
The main portal of the western façade (1342–1498) is one of the most outstanding features of the church. The main tympanum, depicting 21 scenes of the life of Saint-Mary is framed by a quintuple row of sculpted archivolts, each representing several dozens of other biblical scenes, while the smaller tympana below (the northern one depicting the Crucifixion of Jesus and the southern one depicting the Birth of Christ and the Adoration of the Magi) are framed by a double row of archivolts, also depicting biblical scenes. The portal is further decorated on all sides by larger than life statues of saints displaying their attributes or acting out scenes.
The north side of the church also presents a remarkable, if somewhat smaller portal (1415), less ornate as for its sculptures but architecturally more elaborate. The outside walls of the church are decorated all around by a total of 87 statues of saints.
Another striking feature of the church is the multicolored tile roof, not unlikely to the neighbouring St. Martin church's in Colmar.
The inside of the church is as richly ornate as the outside. The choir is the most decorated part: stained glass windows (15th century), stalls (1442, expanded 1902–1906), 12 statues of Apostles (15th century), Baroque paintings (1719 and 1733). Other parts of the church display statues (Virgin with child, 1510; Saint Ubald, 16th century; Jesus bearing the cross, 17th century), remains of frescoes (15th and 16th century), a baptismal font from the 16th century, a pulpit of 1629 and several Gothic revival statues and altars.
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.
