Roman Catholic Diocese of Montalto
former Latin Catholic diocese in Italy

The Diocese of Montalto (Latin: Dioecesis Montis Alti) was a Latin Church ecclesiastical territory or diocese of the Catholic Church located in the town of Montalto delle Marche in the Province of Ascoli Piceno in the Italian region of Marche. The diocese was erected in 1586 by Pope Sixtus V (Felice Peretti di Montalto), a native of the town. The diocese was suppressed in 1986, and its territory was assigned to a new entity, called the Diocese of San Benedetto del Tronto–Ripatransone–Montalto.
Ecclesiastical history
On 24 November 1586, the Diocese of Montalto was established from territory split from the Diocese of Fermo.
In a papal bull of 18 December 1924, Pope Pius XI united the Diocese of Ripatransone with the diocese of Montalto ad personam episcopi. He appointed Luigi Ferri as Bishop of Ripatransone with Montalto, and ordered a change in the title of the bishop to Episcopus Montis alti et Ripanus. In 1980, the diocese of Montalto had a population of only 31,500 persons.
Restructuring
The Second Vatican Council (1962–1965), in order to ensure that all Catholics received proper spiritual attention, decreed the reorganization of the diocesan structure of Italy and the consolidation of small and struggling dioceses. It also recommended the abolition of anomalous units such as exempt territorial prelatures. These considerations applied to Montalto and to Ripatransone as the population migrated in the post-war period to jobs on the coast at San Benedetto.
