The archaeological site comprehends the remains of a medieval castle formerly built on the ruins of the ancient Roman-Etruscan town Axia. The monumental rocky necropolis is rich in evidences ranging from the Etruscan age to the middle Ages.
In a highly evocative environment there is a great number of rocky tombs of the semi-dice type; they show fake doors and a sottofacciata room, dating back between the IV and II century B.C.. Among the others, the Tomba Orioli (II century B.C.) is worth being pointed out: the tomb shows a chamber 17 meters long containing 67 pit-shaped graves.
The Tomba Grande (III century B.C.) is the biggest of dice-shaped rocky tombs in Etruria.
