Roman Catholic Archdiocese of Ancona–Osimo

[1][2] It has existed in its present form since 1986, when the Archdiocese of Ancona was united with the historical Diocese of Osimo.

[5] On 15 August 1972, by the bull Qui apostolico officio, Pope Paul VI created the new ecclesiastical province of Ancona, and granted its archbishop the status of Metropolitan.

In the Roman synod of Pope Eugene II of November 826, it was ordered that Canons live together in a cloister next to the church.

In 876, the Council of Pavia decreed in Canon X that the bishops should enclose the Canons: uti episcopi in civitatibus suis proximum ecclesiae claustrum instituant, in quo ipsi cum clero secundum canonicam regulam Deo militent, et sacerdotes suos ad hoc constringant, ut ecclesiam non relinquant et alibi habitare praesumant.

In 1179, however, Pope Alexander III issued a bull, confirming the Archdeacon and his colleagues in the Chapter all the rights, privileges and property which they possessed.

In the bull he mentions their right to offerings made at certain altars in the cathedral, which had been granted by Bishops Transbertus, Marcellinus and Bernardus.

[16] The Collegiate Church of S. Maria della Piazza in Ancona was also served by a Chapter, composed of a Provost and six Canons.

[17] A diocesan synod was an irregularly held, but important, meeting of the bishop of a diocese and his clergy.

[21] Cardinal Giovanni Battista Bussi (1710–1726) presided over a diocesan synod in the cathedral at Ancona on 15–18 September 1726.
