The Archaeological Museum is located off the Piazza della Santísima Annunziattta. The museum features a beautiful garden planted with Lebanon cedars, pines, cypresses, tamarisk, and magnolias. It is an outdoor museum with columns, sculptures, tombs, and vestiges of monuments of the ancient Etruscan civilization. The pieces of the Etruscan, Greek, Hellenistic, and Roman civilization held here have previously been preserved in the Palazzo Vecchio, the Uffizi Gallery, and the Palazzo della Crocetta.
There are three sections in the archaeological museum- the Etruscan Topographic Section, the Etruscan-Greek-Hellenistic-Roman Section and the Egyptian Section. These sections contain ancient sculptures, medallions, portraits, clothes, urns, and sarcophagi.
