The Alban Hills are the caldera remains of a quiescent volcanic complex in Italy, located 20 km (12 mi) southeast of Rome and about 24 km (15 mi) north of Anzio. The 950 m (3,120 ft) high Monte Cavo forms a highly visible peak in the centre of the caldera, but the highest point is Maschio delle Faete approximately 2 km (1.2 mi) to the east of Cavo and 6 m (20 ft) taller. There are subsidiary calderas along the rim of the Alban Hills that contain the lakes Albano and Nemi. The hills are composed of peperino, a variety of tuff that is useful for construction and provides a mineral-rich substrate for nearby vineyards.

Monte Cavo, or less often, "Monte Albano," is the second highest mountain of the complex of the Alban Hills, near Rome, Italy. An old volcano extinguished around 10,000 years ago, it lies about 20 km (12 mi) from the sea, in the territory of the comune of Rocca di Papa. It is the dominant peak of the Alban Hills. The current name comes from Cabum, an Italic settlement existing on this mountain.
