The Archaeological Collection - Pallavicini Collection of Trequanda is located on the upper floor of the building that houses the “Dino Galluzzi” Multipurpose Room. It was sold to the Municipality in 2011 by the economist Giancarlo Pallavicini whose name it bears.

Being just over 200 pieces, the exhibition allows the visitor to cancel the distances, embracing all the artifacts with their eyes. The central nucleus of the collection, put together in the nineteenth century, is partly made up of materials from land owned by the family, to which various pieces purchased on the antiques market during the seventies have been added. The initial lot of the Collection includes bronze and ceramic objects from the Villanovan period (IX-VIII century BC), Italo-geometric pottery (late VIII-first half VII century BC), Etruscan-Corinthian (VII-VI century BC) , numerous buccheri (7th-6th century BC), Etruscan black-figure vases (late 6th-early 5th century BC). They are all materials ascribable to a production of the southern Etruscan area, probably circumscribable to the Vulcente hinterland and perhaps to the Visentina area.

Furthermore, in the Pallavicini di Trequanda Collection there are ceramics of Greek origin which are among the materials that circulated in the Etruscan area (5th century BC) and various ceramic specimens from southern Italy, with a strong presence of finds produced in northern Puglia.
