Capriola hill is located to the south of Bolsena on the eastern side of Lake Bolsena. In ancient times Bolsena was part of Etruria. In addition to remains of Etruscan structures there is a distinct site representing a hamlet of the Apennine Culture that was occupied continuously from the late Neolithic through the Eneolithic, indicating that the population existed before the Apennine and adopted it by cultural diffusion. Excavated by Bloch in 1958 the site evidences wattle-and-daub huts with thatched roofs supported by internal poles. The huts were about by placed on rock-cut foundations. They were surrounded with stone walls for individual defence.
