Set up in some rooms of the Town Hall, the museum was inaugurated in 1996 to display the finds found during various excavation campaigns in the Grammichele area.
In the entrance hall, educational panels illustrate the history of archaeological research.
A fragment of an Aeolian capital from the Terravecchia-Casa Cantoniera necropolis, reused as a manhole cover for an archaic Greek tomb, is on display here.
The second room displays prehistoric finds from the areas of Madonna del Piano and Terravecchia-Poggio dei Pini.
In the third room there are some funerary objects from the necropolis of Terravecchia and Casa Cantoniera.
This is followed by a collection of Attic black-figure cups, statues depicting deities from the underworld, and a fragment of a large bust of Demeter with a crown hairstyle.
The museum also exhibits some ceramics from the 15th and 16th centuries with plant or anthropomorphic motifs.
