CASSANO ALL’ IONIO, a town of Calabria, Italy, in the province of Cosenza; its railway station (6 m. S. of the town) is 37 m. N. by E. from the town of Cosenza, while it is 6 m. W. of Sibari, on the line between Metaponto and Reggio. Pop. 6842. It is very finely situated, 820 ft. above sea-level: the rock above it is crowned by a medieval castle commanding beautiful views: a tower is still pointed out as that from which the stone was thrown which killed Milo, but this rests on an erroneous identification of Cassano with the ancient Compsa (q.v.). There are warm sulphurous springs here which are used for baths.
