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, and was the original on which the monastery in Umberto Eco's novel The Name of the Rose was based, together with Sacra di San Michele.
