Castelnovo Monti is a town and comune in the Province of Reggio Emilia, central Italy. Along with every other town and village in the Apennines, Castelnovo is an approved area for the production of Parmesan cheese. It is also home to the only hospital in the area. It is situated in the Reggiano Apennines mountains.
Castelnovo is best known for the Pietra di Bismantova spur. The pietra (literally "Rock of Bismantova") can be spotted from a distance of 30 km (19 mi) as it stands at around 1,047 m (3,435 ft) above sea level. The rock is a favourite climbing and abseiling destination throughout Italy and is considered a particularly difficult climb due to its outward-curving wall. The rock was mentioned by the Italian poet Dante Alighieri in the Divine Comedy.
