BRUGNATO. — In Liguria, in the province of Genoa. There flourished a Benedictine monastery, whose foundation is attributed to the Lombard king Liutprand, in honor of Sts. Peter, Lawrence, and Columbanus; it received privileges from Popes Gregory III, John XIII, and Benedict VII, and from the Lombard kings Aistulf and Desiderius, and from the emperors Charlemagne and his successors, the three Ottos, and Henry II in 1014. Innocent II in 1133 suppressed the abbey and erected the diocese of B., elevating the abbot Peter to bishop, and made it a suffragan of Genoa. Gregory IX united it with Noli, an union annulled in 1245 by Innocent IV; in 1787 a large part of the diocese was detached when Pius VI established the bishopric of Pontremoli; in 1820 it was united *aeque principaliter* with the diocese of Luni (q.v.) and Sarzana.
