During the Etruscan era, the hills that extend from Marsiliana to the southeast towards Capalbio were the site of a number of burial grounds, composed mainly as clusters of mostly small chamber tombs. This construction is a sign of both of the population density of the area as well as its proximity to the ancient road network connecting Vulci and Caletra, itself an outgrowth of a ford on the River Albegna. Poggio Pietricci is the only one of these burial clusters that has been investigated and unearthed by the sopraintendenza, or cultural ministry. To date, eleven graves have been identified: these plots were dug directly into the rock and consisted of a simple square room preceded by an access corridor and sometimes surrounded by a circle of stones, perhaps to indicate the presence of a burial slab. The recovered materials demonstrate the use and practice of burials in the second half of the 7th and the first half of the 6th century BC.
