Patriarchal Cathedral St. Andrew

The Cathedral of St. Andrew the Apostle, also known as the Pitsunda Cathedral or Bichvinta Cathedral is an Eastern 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 schismatic Abkhazian Orthodox Church and serves as that body's seat, although this usage is disputed by the Georgian Orthodox Church and is considered irregular by the Eastern Orthodox communion generally.

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.
