Cittaducale (locally Cieta) is a comune (municipality) in the Province of Rieti in the Italian region Lazio, located about 70 kilometres (43 mi) northeast of Rome and about 7 kilometres (4 mi) southeast of Rieti.

[3] The municipality of Cittaducale contains the frazioni (subdivisions, mainly villages and hamlets) Santa Rufina, Grotti, Calcariola, Pendenza, Cesoni, and Micciani.

Cittaducale borders the following municipalities: Borgo Velino, Castel Sant'Angelo, Longone Sabino, Micigliano, Petrella Salto, Rieti.

However, after the cardinal's death and at the request of the bishop of Rieti, the same pope restored the diocese on 16 October 1508.

[4][5] No longer a residential bishopric, Cittaducale is today listed by the Catholic Church as a titular see.
