Buthrotum was an ancient Greek and later Roman city and bishopric in Epirus. Inhabited since prehistoric times, Buthrotum was a city of the Greek tribe of the Chaonians, later a Roman colony and a bishopric. It entered into decline in Late Antiquity, before being abandoned during the Middle Ages after a major earthquake flooded most of the city. In modern times it is an archeological site in Vlorë County, Albania, some 14 kilometres south of Sarandë and close to the Greek border. It is located on a hill overlooking the Vivari Channel and is part of the Butrint National Park. Today Bouthrotum is a Latin Catholic titular see.
