Bobbio Abbey (Italian: Abbazia di San Colombano) is a monastery founded by Irish Saint Columbanus in 614, around which later grew up the town of Bobbio, in the province of Piacenza, Emilia-Romagna, Italy. It is dedicated to Saint Columbanus. It was famous as a centre of resistance to Arianism and as one of the greatest libraries in the Middle Ages. The abbey was dissolved under the French administration in 1803, although many of the buildings remain in other uses. History Foundation The background to the foundation of the abbey was the Lombard invasion of Italy in 568. The Lombard king Agilulf married the devout Roman Catholic Theodelinda in 590 and under her influence and that of the Irish missionary Columbanus, he was persuaded to accept conversion to Christianity. As a base for the conversion of the Lombard people Agilulf gave Columbanus a ruined church and wasted lands known as Ebovium, which, before the Lombards seized them, had formed part of the lands of the papacy. Columbanus particularly wanted this secluded place, for while enthusiastic in the instruction of the Lombards he preferred solitude for his monks and himself. Next to this little church, which was dedicated to Saint Peter, a monastery was soon built. The abbey at its foundation followed the Rule of St. Columbanus, based on the monastic practices of Celtic Christianity. 7th century Columbanus was buried on 23 November 615, but was followed by successors of high calibre in Attala (d. 627) and Bertulf (d. 640), who steered the new monastery through the threats from militant Arianism under King Rotharis (636–652). In 628, when Bertulf made a pilgrimage to Rome, he persuaded Pope Honorius I to exempt Bobbio from episcopal jurisdiction, thus making the abbey immediately subject to the Holy See. Under the next abbot, Bobolen, the Rule of St. Benedict was introduced. At first its observance was optional, but in the course of time it superseded the stricter Rule of Saint Columbanus, and Bobbio joined the Congregation of Monte Cassino. In 643, at the request of Rotharis and Queen Gundeberga, Pope Theodore I granted to the Abbot of Bobbio the use of the mitre and other pontificals. During the turbulent 7th century and through the efforts of Columbanus's disciples, increasing numbers of Arian Lombards were received into the Catholic form of Christianity. However, during the first half of the 7th century, the large tract of country lying
