The first mention of a church in Konstanz dedicated to the Virgin Mary was in 615. Documentary confirmation of the Episcopal church is dated to the mid 8th century. There is clear evidence indicating that it was located on the Cathedral Hill, where a late Romanesque fortification with an adjoining civilian settlement had been established. In 780, the church was mentioned in a confirmation of a contract by Charlemagne.
St. Maurice’s Rotunda (Holy Sepulchre) was built in 940 on orders of Bishop Konrad (934 - 975) who was canonized in 1123. In 1052, the cathedral collapsed. Its reconstruction took place under Bishop Rumold (1051 - 1069), with the eastern transept and three naves separated by 16 monoliths. The next 300 years saw the construction of one towers, then another, then a great fire destroyed one of the towers along with parts of the basilica as well as 96 other houses in the city. The south tower was completed in 1378.
From 1414 to 1418 the Council of Constance took place. The most important assembly of the Church during the Middle Ages, and the only one on German soil. Martin V, who had been elected Pope by the Conclave and thereby ending the schism dividing the Church, is enthroned in this Cathedral in 1417. In 1415 Jan Hus, because of his teachings, was condemned as a heretic by the Council who, at this time, was without a Pope. He was then delivered to the secular power who condemned him to death, tied him to a stake and publicly burnt him alive.
Between 1418 and 1525, the Cathedral was adapted to Gothic style by master craftsmen. In the period from 1526 to 1551, the Bishop left Konstanz because of the Reformation, and moved his See across the lake to the Martinsburg in Meersburg. The radical iconoclasm instigated by the reformer Huldrych Zwingli in nearby Zurich, caused the destruction of artwork in the Cathedral.
The subsequent centuries saw the addition of more paintings, wrought iron gates and sculptures, as well as the replacement and repair of destroyed items. Of note is the replacement of the painted Romanesque wooden ceiling by brick vaulting in 1637.
In 1821, Konstanz's bishopric, the largest in Germany, was dissolved and, in 1827, moved to Freiburg in the Breisgau. It had served the people around Lake Constance (Bodensee) for 1200 years, and survived almost 100 bishops. General restoration work took place on the Cathedral from 1844 to 1860; the tower was raised in neo-Gothic architectural style.
In 1955 Pope Pius XII raised the Cathedral to a papal Basilica Minor. A restoration program of the Cathedral’s interior as well as exterior was started in 1962 and is expected to be completed by 2010. In 1966, twelve new bells were cast and hung in the center tower and the ridge turret, a present from the state of Baden-Württemberg.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.
