Saint Sophia Greek Orthodox Cathedral was founded as a church in 1904 to serve the Greek Orthodox residents of the District of Columbia. In 1962, the church was elevated to a cathedral. The building is in the Neo-Byzantine style with a central dome that reaches 24m in height.
The congregation met in temporary quarters for several years, prior to the construction of its own church near 8th and L Streets NW which was dedicated in 1924. This site is currently occupied by the Walter E. Washington Convention Center. Construction on the current edifice at 2815 36th Street NW, near Massachusetts Avenue and a short distance from the Washington National Cathedral, began in 1951. The congregation began worshipping there in 1955 shortly after major construction was completed. Although the building has been in use for over fifty years, the interior decoration is incomplete. Work began on the interior in 1965 and continues to the present.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
