but by the 11th century it was concentrated on the Eastern Height, now surrounded by a double bank and ditch. In the 12th century, a tower was built in the centre of these fortifications, with a large cistern on two sides. That this cistern was subsequently used as a prison is suggested by graffiti on its plaster lining, one of which gives the date of 1211. The castle, belonging to the Aldobrandeschi family in 1269, was destroyed by the Sienese army in 1329, on the pretext that it was occupied by bandits. A catapult or trebuchet base found on the Eastern Height may have formed part of the defences at this time. The site remained deserted after this time. Settefinestre A large villa complex in the Ager Cosanus at Settefinestre was excavated by Andrea Carandini in the 1970s. See also For the "Port of Cosa", Amphora Industry, see Fish sauce, and garum.
