Pacentro, a municipality of the province of L’Aquila in Abruzzo, is a well preserved historic medieval village located in the central part of Italy, several kilometres from the City of Sulmona about 170 km east of Rome. Pacentro lies in the Apennine Mountain Range on a plateau consisting of small hills 650 m above sea level.
The castle sits on one hill (Colle Castello) at one end of town and the other hill (Colle San Marco) is where the old Church of San Marco used to sit. The town is just below Mount Morrone and just above the Peligna Valley (Conca Peligna) and the City of Sulmona.
Pacentro is part of the Majella National Park (Parco Nazionale della Majella) and is renowned for its springs and fresh mountain water that comes from the snow of the Majella.
