Chiusi

Chiusi (anc. Clusium), a town in the province of Siena, Tuscany, Italy, stands on a hill close to a lake bearing the same name. It was Porsenna's capital and one of the twelve cities of the Etruscan Confederation. Consequently large numbers of vases, mirrors, bronzes, and other interesting traces of that extinct race have been found here. A place of some importance in the Roman period, it declined in the Middle Ages, the spread of the neighbouring marshes causing malarial fever. These have now been drained, and the population is increasing.
