Borsh Castle (Albanian: Kalaja e Borshit) also known as Sopot Castle (Albanian: Kalaja e Sopotit) from the hill it is located, is a ruined castle near the village Borsh, Albania, near the coast of the Ionian Sea. Inside the castle is the 17th-century Hajji Bendo Mosque from Ottoman times.
The castle dates to Antiquity, and its fortifications follow the trace of an acropolis, with four subsequent phases of reconstruction, ranging from the early Byzantine period to the late Middle Ages. The name "Sopot" is of Slavic origin. In medieval Greek documents, the castle is named Sopoton or Sopotos, from which its name in other languages derives; its harbour is mentioned in Greek portolans with the name Gazopolis.
The site is first mentioned in the early 13th century, when archbishop Demetrios Chomatenos wrote of the "archonship of Sopotos" (Greek: ἀρχοντία Σοπωτοῡ, archontia Sopotou), part of the region of Vagenetia. In 1258, the Despot of Epirus Michael II Komnenos Doukas gave the castle along with Buthrotum and the island of Corfu as dowry for his daughter Helena to Manfred, King of Sicily. It came back under Epirote control soon thereafter, before being once again ceded by Nikephoros I Komnenos Doukas to Charles I of Anjou in 1279. The area returned again to Epirote hands in the subsequent decades, but in the Epirote rebellion against Palaiologan Byzantine rule in 1338–39, it remained loyal to Emperor Andronikos III Palaiologos.
Kaninë Castle (Albanian: Kalaja e Kaninës) is a castle in the village Kaninë near Vlorë, in southwestern Albania.
This castle was built in the village with the same name which is about 6 kilometres (4 mi) from Vlorë. The castle rises on the side of the Shushica Mountain, about 380 metres (1,250 ft) above sea level. The castle was built on the site of an ancient settlement, one of the oldest in the Vlora region. The castle is believed to have been erected in the 3rd century B.C. In the 4th century B.C. the castle was transformed into a fortress town. In the 6th century A.D. the castle was reconstructed by Justinian I. The castle was the center of the Principality of Valona in the 14th century.
