The city is beside the sea, between the Modione River (the ancient Selinus) in the west and the Cottone River in the east, on two high areas connected by a saddle. The part of the city to the south, next to the sea, contains the acropolis which is based around two intersecting streets and contains many temples (A, B, C, D, O). The part of the city to the north, further inland, contained housing on the Hippodamian plan contemporary with the acropolis and two necropoleis (Galera-Bagliazzo and Manuzza).
