The former Italian Catholic diocese of Bisignano, in Calabria, existed from the eighth century until 1818.
[1][2] Bisignano is the ancient Besidias, or Besidianum, which in the eleventh century became the residence of a Norman count and later a fief of the Orsini.
In 1467 Skanderbeg's daughter, wife of the Prince of Bisignano, invited there many Albanian families who established various colonies, spoke their own language, and used the Greek Rite.
Bisignano certainly had bishops in the tenth century, when mention is made of Ulutto in the life of St. Uilo di Rossano; Bishop Federico (1331) was killed in 1339.
