The Montecopiolo castle was built in the 10th century on the homonymous mountain relief at the behest of the bishops of Montefeltro or their emphyteutes (the Counts of Carpegna). It is located upstream of today's hamlet of Villagrande di Montecopiolo, the municipal capital of the municipality of Montecopiolo (province of Rimini), in the Montefeltro area. The remains of the castle are located at an altitude of 1,033 m a.s.l. at the watershed between the valleys of the Conca and Marecchia rivers. The area occupied by the castle reached 9,000 m².
