The top floor of the museum houses the suggestive section on the Etruscan symposium; here the visitor is virtually invited to visit the home of an Etruscan prince "Aranth"; it is therefore possible to see the life-size reconstruction of the banquet hall with the triclinia where the Etruscans ate their meals together with their wives, causing a great scandal for the customs of the time; the room also displays various ritual and everyday objects related to the consumption of food, in particular meat and wine, a drink then associated with contact with the divine. In the other room, finds from the excavations of a thermal complex from the Augustan age are on display, where the poet Horace came to be treated with the waters of Chianciano. Here there are also some display cases with finds donated by citizens to the Museum; also in this room, a balustrade offers a particular point of view of the pediment of the Fucoli temple located on the lower floor.
