The Diocese of Ozieri (Latin: Dioecesis Octeriensis o Othierensis) s a Latin Church diocese of the Catholic Church in Sardinia, Italy. It is a suffragan of the Metropolitan Archdiocese of Sassari.[1]
The historical Diocese of Bisarchio was in the province of Sassari, district of Nuoro, with the episcopal residence at Ozieri. The first bishop mentioned is Costantino Madrone (c. 1102), who was succeeded in 1116 by Bishop Pietro. The cathedral was built in 1153. The bishop's residence changed several times, to Giracle, and again to Ardera.
In 1503, at the death of Fra Calcerando, bishop of this see, Bisarchio was incorporated into the diocese of Alghero. The diocese was reestablished by Pope Pius VII in his Bull of 9 March 1803, and given to Giannantioco Azzei, in 1819 archbishop of Oristano, his native place. The episcopal residence was then definitely transferred to Ozieri.[2] The change of name took place in 1915.
