In the 19th century, on the "Monterozzi" hill there were approximately 600 burial mounds that today are almost completely disappeared because razed to the ground by the ploughing that saved, as we can see in this area, only the stone border that contained the mount of earth. This sector of the necropolis is interesting because of the presence of burial rooms with mounds achieved with different techniques.
The underground burial chamber was entered through a descending corridor (dromos) with a chute  or a stairway. After the deposition of the deceased the room was closed and the dromos filled with earth.

The tomb of the "Panthers" - Distinguished by a mound, the tomb of the "Panthers" is currently the oldest evidence of tomb painting in Tarquinia before the great archaic period of Greek-Ionic influence, of which Tarquinia will be the Etruscan capital.
A steep dromos enters a narrow room with two benches for the deposition of the deceased. The decoration is limited to the end and to the entrance walls; on the end one there are two big felines in profile (the left one with the head in a prospect view), opposed in heraldic pattern and with the paws on the monstrous head of another feline. The wild animals are a menacing representation of the world of the dead, so different from human nature.

The tomb is dated to the final years of the 7th century BC. The fresco style, with large animals that are not adapting well to the room architecture, betrays the hand of a vessel painter not used to work on large surfaces and shows the important role played by potters in the early experiences of the Etruscan tomb painting.
