These rooms, conventionally called of the terra-cottas, are dedicated to Etruscan temple and votive terra-cotta work. The large area of room 6 is well suited to recreating a stimulating space in many ways similar to the ancient sacred areas, where a perimetral wall enclosed the high podium on which the temple was built and a square in the foreground, scattered with votive offerings and altars. Numerous architectural terra-cottas are on display. These are of various origins. It has been proposed for some of them to have a reconstructive exhibition on supports alluding to the wooden covering of the roof that they decorated in ancient times.
Votive offerings in terra-cotta are displayed on the dais in the middle of the room and in the showcases along the left wall. In the majority of cases they come from one or more temples of the city of Caere (Cerveteri), and are mainly dated to the end of the 4th-3rd cent. BC. The exhibition is aimed at emphasizing not only the artistic quality of the votive offerings, but also the great variety and quantity of gifts that were brought daily to the temple. The ancient shrines were normally in fact overloaded with ex-votos. Everything was donated, preferably small models of the cult image, more often reproductions of parts of the human body (heads, half heads, limbs, organs) or of food or sacrificed animals.
