The tumuli are circular structures built in tuff, and the interiors, carved from the living rock, house a reconstruction of the house of the dead, including a corridor ("dromos"), a central hall, and several rooms. Modern knowledge of Etruscan daily life is largely dependent on the numerous decorative details and finds from such tombs. One of the most famous tombs is the Tomb of the Reliefs, identified from an inscription as belonging to the Matuna family and provided with an exceptional series of frescoes, bas-reliefs and sculptures portraying a large series of contemporary life tools.
