The Saint Sebastian Church is a 16th-century church in central Madrid. The name arises from a devotional chapel which was found along the route to the Basilica of Nuestra Señora de Atocha, founded in 1541. The first architect around 1550 was Antonio Sillero, who also finished the Chapel of the Sagrado Corazón. This church like that of San Luis conserved for years the rights of asylum for those escaping official persecution. More chapels and enlargements were added by Antonio de la Tijera, Juan de Bulga Valdelastras, and Juan de Obregón between 1595 and 1598. The tower was built in 1612 by Lucas Hernández.
During the Spanish Civil War, the church was sacked by Republican forces, before it ended up being almost destroyed during a bombing raid by the Nationalists around November 20, 1936. This caused many of the works to be transferred to other sites. The church was rebuilt in a different orientation by Francisco Íñiguez Almech between 1943 and 1959.
The Chapel of Our Lady of Bethlehem, known as the 'chapel of the architects', was built in 1693 with Francisco Moreno as director of the works, and remodeled by Ventura Rodríguez in 1766-1768. Both Ventura Rodríguez and Juan de Villanueva are buried here. The chapel is to the right of the entrance, protected by a crystal gate.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.
