The population is distributed between two main settlements, a number of hamlets, and various isolated dwellings: the seat of the municipality is in San Lorenzo (980 m). Fonti (669 m) was also classified as a centro abitato ("populated centre"). Less strongly defined settlements (nuclei abitati) were Graniga (1113 m), Messasca (525 m), and Pizzanco (1142 m). Localities whose population was subject to significant variation during the course of a year were Pioi (850 m), La Gomba (1251 m), and Vercengio (1299 m). Morasco (956 m) is described as a ‘special mountain nucleus’.[2]
