The archdiocese of Santa Severina was a Roman Catholic ecclesiastical territory in Calabria, southern Italy, that existed until 1986.
In that year it was united into the diocese of Crotone, forming the Archdiocese of Crotone-Santa Severina.
[1][2] Santa Severina (῾Αγία Σεβερίνη, Σεβεριάνη), built on a rocky precipice on the site of the ancient Siberena, became an important fortress of the Byzantines in their struggles with the Saracens.
The Greek Rite disappeared from the diocese under the Normans, but was retained in the San Severina cathedral during a great part of the thirteenth century.
Belcastro, considered by some authorities to be the ancient Chonia, had bishops from 1122; noted was Jacopo di Giacomelli (1542), present at the Council of Trent.
