Saint Gatien's Cathedral was built between 1170 and 1547. The first cathedral of Saint-Maurice was built by Litorius (Lidoire), bishop of Tours from 337 to 371 (preceding St Martin). Burnt in 561, it was restored by Gregory of Tours and rededicated in 590. Its location, at the south-west angle of the castrum, as well as its eastern orientation, resulted in the original access being through the late-Roman surrounding wall (such a configuration is quite rare). The cathedral was then rebuilt during the second quarter of the 12th century and again burnt in 1166 during the conflict between Louis VII of France and Henry II of England.
The first phase of present cathedral concerned the south transept and the towers, as early as 1170. The chancel was rebuilt from 1236 to 1279 by Étienne de Mortagne but the nave took much longer to build. The architect Simon du Mans rebuilt the transept and started the nave, including six spans, aisle and chapel, built during the 14th century — the first two spans correspond to those of the old Romanesque cathedral and date back to the 12th century. The nave was only finished during the 15th century by architects Jean de Dammartin, Jean Papin and Jean Durand, thanks to the generosity of Charles VII and the Duke of Brittany Jean V.
While building the present cathedral, the nave was then extended westward and the towers surrounding its entrance were erected during the first half of the 16th century, the first tower in 1507 by Pierre de Valence 87 m high, and the second tower during 1534 and 1547 by Pierre Gadier. Highlighting the special feature of the building, called supra, the towers were erected outside of the old city. The late-Roman surrounding wall is visible in cross section at the rear of the towers from the north.
In 1356, the cathedral received its new name of saint Gatien. Its construction having been particularly slow, it presents a complex pattern of French religious types of architecture from the 13th century to the 15th. For example, the tower buttresses are Romanesque, the ornamentation generally is pure Gothic, and the tops of the towers are Renaissance (beginning of the 16th century).
The organ, donated by Archbishop Martin de Beaune, was built by Barnabé Delanoue in the 16th century. One can also see, in the cathedral, the tomb of the children of Charles VIII and Anne of Brittany, who died as infants. This tomb, in Carrara marble, made by Girolamo da Fiesole, in the Italian style, and whose recumbent statues are reminiscent of 15th-century French medieval tradition (school of Michel Colombe), was kept since 1506 in Saint-Martin de Tours before being moved in 1834 to Saint-Gatien.
To the north of the cathedral is a small cloister, also built during the Renaissance. To the south of the cathedral is the former archbishop's palace, built in the early 18th century, which has now become the Musée des Beaux-Arts de Tours.References:
The Church of Saint Demetrius, or Hagios Demetrios, is the main sanctuary dedicated to Saint Demetrius, the patron saint of Thessaloniki. It is part of the site Palaeochristian and Byzantine Monuments of Thessaloniki on the list of World Heritage Sites by UNESCO since 1988.
The first church on the spot was constructed in the early 4th century AD, replacing a Roman bath. A century later, a prefect named Leontios replaced the small oratory with a larger, three-aisled basilica. Repeatedly gutted by fires, the church eventually was reconstructed as a five-aisled basilica in 629–634. This was the surviving form of the church much as it is today. The most important shrine in the city, it was probably larger than the local cathedral. The historic location of the latter is now unknown.
The church had an unusual shrine called the ciborium, a hexagonal, roofed structure at one side of the nave. It was made of or covered with silver. The structure had doors and inside was a couch or bed. Unusually, it did not hold any physical relics of the saint. The ciborium seems to have been a symbolic tomb. It was rebuilt at least once.
The basilica is famous for six extant mosaic panels, dated to the period between the latest reconstruction and the inauguration of the Byzantine Iconoclasm in 730. These mosaics depict St. Demetrius with officials responsible for the restoration of the church (called the founders, ktetors) and with children. An inscription below one of the images glorifies heaven for saving the people of Thessalonica from a pagan Slavic raid in 615.
Thessaloniki became part of the Ottoman Empire in 1430. About 60 years later, during the reign of Bayezid II, the church was converted into a mosque, known as the Kasımiye Camii after the local Ottoman mayor, Cezeri Kasım Pasha. The symbolic tomb however was kept open for Christian veneration. Other magnificent mosaics, recorded as covering the church interior, were lost either during the four centuries when it functioned as a mosque (1493–1912) or in the Great Thessaloniki Fire of 1917 that destroyed much of the city. It also destroyed the roof and upper walls of the church. Black-and-white photographs and good watercolour versions give an idea of the early Byzantine craftsmanship lost during the fire.
Following the Great Fire of 1917, it took decades to restore the church. Tombstones from the city"s Jewish cemetery - destroyed by the Greek and Nazi German authorities - were used as building materials in these restoration efforts in the 1940s. Archeological excavations conducted in the 1930s and 1940s revealed interesting artifacts that may be seen in a museum situated inside the church"s crypt. The excavations also uncovered the ruins of a Roman bath, where St. Demetrius was said to have been held prisoner and executed. A Roman well was also discovered. Scholars believe this is where soldiers dropped the body of St. Demetrius after his execution. After restoration, the church was reconsecrated in 1949.
