The town became of importance when the Monastery of San Colombano was established in 614. During Medieval times its library became one of the most important in Europe. Also of interest is the Malaspina Dal Verme Castle, another medieval architectural jewel. Since 1995, every summer the wonderful Bobbio Film Festival is held inside the Monastery of San Colombano by the film director Marco Bellocchio. Down towards the valley, along the course of the river Trebbia, visitors can navigate the Strada di Vini e dei Sapori dei Colli Piacentini (the Road of Wine and Flavours of the Piacentini Hills) to discover local wineries and the many products of this area.
