CITTÀ DELLA PIEVE, DIOCESE of. - In Umbria, in the province of Perugia. The ancient Castrum plebis belonged to the extensive diocese of Chiusi, from which it was detached when it was created an independent bishopric in 1601 by Clement VIII, who also conferred upon it the title of city. It is a suffragan of Perugia.
Subjected by Pope Martino V (1417–31) to the State of the Holy See, it was later placed under his direct rule and annexed to the legation of Perugia in the reorganization of 1816.
Noteworthy is the Cathedral, a Romanesque-Gothic building of the 11th–12th centuries, though with a Baroque interior. It is the birthplace of Perugino (Pietro Vannucci, 1446–1523), who left there several of his works, such as the Epiphany, a fresco of 1504 in S. Maria de' Bianchi, and several panels in the Cathedral.
The diocese has an area of 350 sq. km.; it comprises 33 parishes, 47 priests, and 45,000 inhabitants, all Catholic (1948).
