The Castello di Bossi is located in the commune of Castelnuovo Berardenga, on the road that leaves the old Chiantigiana road, at Pianella, and ascends to Brolio amidst evergreen forests and long rows of vines. With its centuries-old trees, its fossil beds, and richly varied native vegetation, this unique spot has always aroused curiosity, even in remote times, and experts have studied its characteristics. The name Bossi would seem to derive from the money chest which the Roman army would carry to its encampments to pay the soldiers; the word probably refers to the boxwood, a rare and prized wood at that time, from which the chest was built. Inscriptions dating from the 1st and 2nd centuries AD, discovered in an ancient wall of the canonry in San Marcellino, indicate that this area was the site of a Roman settlement.
