Located in the heart of the Sibillini Mountains, in the region of Umbria, Castelluccio di Norcia, as its name suggests, is a hamlet of the municipality of Norcia, the city famous for being the birthplace of Saint Benedict.

The village stands on the top of a small hill at 1452 metres above sea level, in the middle of an extensive plain - or Piana di Castelluccio - where the characteristic lentil is grown. Dominated by the 2476-metre-high Monte Vettore, the Piana di Castelluccio is a vast plain at 1270 m above sea level that occupies 15 km2 of plateau divided into three plains: Pian Grande, Pian Piccolo and Pian Perduto.
