Caliabria was a city and the seat of a diocese founded in the 7th century in Visigothic Spain and is now a Latin titular see of the Catholic Church.
[3] However, Coura, near Viseu, and Fermoselle near Zamora each have a champion, as do Vilanova de Foz Côa and Castelho Melhor, places closer to the generally accepted location.
The exact date of its erection as a diocese under the Visigoths is disputed, one scholar placing it after 621, while another thinks it occurred in the reign of Witteric (603-610),[3] or it may be as early as 569, under the Suebi.
In 1161, King Ferdinand II of León founded the Diocese of Ciudad Rodrigo, while granting the defunct city's territory to that city, perhaps claiming, because of opposition raised by the civil and ecclesiastical authorities of Salamanca, that the new diocese was a revival of that of Caliabria, a title generally used by the first bishop, but not by his successors, by whose time agreement had been reached with Salamanca.
However the papal bulla Ex litteris, by which Pope Alexander III confirmed in 1175 the erection of the diocese of di Ciudad Rodrigo, mentions neither Caliabria nor a restoration.
