Château de Boutavent may have been built in the 11th century, but there is no written evidence of exact date. It has been confirmed that during the 13th and 14th century, the castle belonged to the Lords of Montfort. According a legend during the 7th century the castle was the residence of Judicaël, King of Domnonée, and that it had been the place where the King and saint Éloi met. This last was sent to bring peace in a fight for borders between Bretons and French.
The castle is structured into two classical elements: a courtyard and a barnyard, separated by a deep gap. Four buildings which could be guesthouses, are on both sides of the barnyard. The fortification and elements of the barnyard can still be seen.
In the 16th century, the castle was already ruined. The circumstances of the destruction of the fortified site of Boutavent remain mysterious. Maybe it has been dismantled during the War of succession (second half of the 14th century) or in 1373, during the campaign of Bertrand du Guesclin in Brittany, but nothing proves that the castle hasn't been inhabited then.
Many local authors of the 19th century wrote about Boutavent, in particular writers like Poignand, Vigoland or Oresve. Even though these stories constitute rare stories about the site, it is impossible to retrace the entire history of the castle, as there are only a few sources.
The castle has not been searched yet but many campaigns of consolidation of the relics took place since 2006. During these campaigns, archaeological material has been found (slate, ceramic, ground pavement and glazed tiles).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.
