The Italian Catholic diocese of Lacedonia (Laquedonia, Cedonia), a suffragan of the archdiocese of Benevento in Campania, existed until 1986 when incorporated into the reorganized Roman Catholic Diocese of Ariano Irpino-Lacedonia.
[1][2] The bishop of Lacedonia had his episcopal throne in the cathedral of Lacedonia, which was dedicated to the carrying up (Assumption) of the body of the Virgin Mary into heaven.
The cathedral was administered and served by a Chapter, which consisted of five dignities and seven Canons.
In the great earthquake of 1456, the town of Lacedonia was completely ruined and abandoned.
[6] Recovery was assisted by the Prince of Taranto, Gianantonio Orsini.
