This small rather beautiful municipality situated on the seaside, consists of 17 hamlets scattered in one valley in "U".
Inside the hamlet San Martino, the highest of 17 Sisco's hamlets, is the Church Martinmas which possesses within it numerous reliquaries of the XII and XIII centuries. Built on a crypt, this brooding is remarkable by its decorations of oriental potteries as well as for its strengthened tower.
