It lies in the Bolognese Apennines, near the border with Tuscany, about 40 km (25 mi) south-west of Bologna. The town takes its name from the Pepoli family of Bologna, who controlled the territory for several centuries after acquiring it in the 14th century. Castiglione dei Pepoli developed as an Apennine settlement between Emilia and Tuscany, in a strategic position along routes connecting Bologna and Prato. The municipality is characterised by chestnut and fir woods, mountain landscapes, pilgrimage sites, small artificial lakes and historical infrastructure linked to the Bologna–Florence railway.
