Situated along the ancient Roman road Aurelia, Venturina Terme is a modern town developed around industrial, agricultural, commercial and thermal activities.

Since the early 20th century, thanks to the drainage of the marshes and the development of Piombino's industrial area, the town gradually began to expand and increase its population.

The sarcophagus, today missing, contained human remains of a prominent figure in connection with the Roman society settled in the nearby town of Populonia and was supposed to be located close to the opening at the base of the structure.

In 1964, Father Enrico Lombardi suggested to associate the sepulchre with Caius Trebatius, a Roman aristocrat whose name was inscribed in a signet ring found in the vicinity of Venturina, though this attribution remains purely an assumption.

The exhibition is hosted inside the trade fair zone in Venturina Terme and is maintained by volunteers of a local association.
