Sant'Angelo in Vado in 1635 became a city, and then an episcopal see.
Urbania in 1280 was demolished by the
Ghibellines. It was restored again by the Dominican bishop,
Guglielmo Durante and called Castel Durante; it was included in the
Duchy of Urbino, and contained a magnificent ducal palace. At the beginning of 1635 S. Angelo was an
archpresbyterate nullius, subject to the Abbot of the
Monastery of S. Cristoforo of Castel Durante, to whom the Archpresbyterate of Castel Durante was also subject. In that year
Pope Urban VIII erected the two towns into dioceses, changing the name of Castel Durante to Urbania, and uniting them
aeque principaliter under
Onorato degli Onorati, who governed it for forty-eight years. Other bishops were: Gian. Vincenzo Castelli, O.P. (1711), who restored the cathedral of Urbania, and Paolo Zamperoli, O.P. (1779) sent into exile under Napoleon, dying there. ==Ordinaries==
