This neolithic era (3500-2700 BC) burial site consists of thirty caves carved closely together on an outcrop of very soft limestone rock. Partial excavation in the 1970s by the archaeologist Ferrante Rittatore Vonwiller unearthed some of the characteristic tools used by the Rinaldone culture, such as “flask” type mixing jars and flint arrowheads. The materials are now on display in the Manciano Museum of Prehistory.
