The museum was established in 1992 to house archeological artefacts from the Etruscan city of Veio, which was subjugated by the Romans in 396 and subsequently became the site for the Municipium Augustum Veiens.
It is presently in temporary housing awaiting 2011 when it will be definitively rehoused in Palazzo Chigi which was the site for the Museum of Natural, Ancient and Bizarre Curiosities during the second half of the 16th century, at the time of Cardinal Flavio Chigi, which contained numerous archeological artefacts from the first excavations carried out in the Agro Veientano area.
The temporary museum holds Etruscan and Roman ceramic artefacts, several votive statues, stone materials including an altar dedicated to  the family gods (I Lari) and other funeral inscriptions, slabs of ‘Campana’ type terracotta and toilette articles in bronze.  The marble sculpture relics include ‘The Emperor’ a virile, headless, statue from the Julian-Claudian era which probably belonged to the Chigi colleciton, a headless statue dating to the Antonine period from the domus culta of Capracorum, a 2nd century sarcophagus and a  2nd century statue of Priapus known as ‘Il Maripara’ which is a rare example of a lifesize statue of the god.  The exhibition also holds some medieval and renaissance objects that were found during the recovery and excavation work carried out in the centre of Formello.
The basement floor of the Palazzo already holds ample space for conferences and exhibitions – the Sala Orsini - while the section of the museum housed in the ex-wash house houses the Centre for Incision and Graphic Arts, which is focussed on temporary exhibitions, conferences and teaching courses on the art of incision.
