The Pitsunda or Bichvinta Cathedral is a Georgian Orthodox Cathedral located in Pitsunda, in the Gagra district of the de facto independent Republic of Abkhazia, internationally recognised as constituting a part of Georgia. The cathedral is currently used by the Abkhazian Orthodox Church and serves as that body's seat, although this usage is disputed by the Republic of Georgia and is considered irregular by the Eastern Orthodox communion.
Pitsunda Cathedral was built at the end of the 10th century by King Bagrat III of Georgia. It served as the seat of the Georgian Orthodox Catholicate of Abkhazia until the late 16th century when Abkhazia came under the Ottoman hegemony. According to 17th century French traveller Jean Chardin, Catholicos, who no longer lived in Pitsunda, visited the cathedral once a year with the retinue of bishops and princes to perform the sanctification of chrism. The cathedral was reconsecrated in 1869 when Abkhazia was already a part of Russian Empire.
It is a cross-domed cathedral with three naves and three apses, shaped as a rectangle with extending semicircular apses. The cathedral is notable for its impressive size, reaching 29 m high (including the dome), 37 m long and 25 m wide; the walls are up to 1.5 m thick. The building rests on heavy slabs of grey sandstone; the walls are made up of alternating rows of stone and brickwork, a typical technique for late Byzantine architecture. The cathedral contains vestiges of wall-painting from the 13th and the 16th centuries. A 12th-century Georgian manuscript of the Four Gospels, found at the cathedral in 1830, is now preserved at the Georgian National Center of Manuscripts in Tbilisi.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
