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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
