The Sopot Fortress was probably built at the beginning of the 13th century. In 1258 Sopot became a part of Manfred of Hohenstaufen's realm and was conquered by Nikephoros I of Epirus in 1278 but ceded to the Anjou in 1279. During the Rebellion of the Albanians in 1336 Sopot supportet the Byzantine emperor Andronikos III. It was again mentioned in 1431-1432 in the Ottoman Defter.
