Megalithic walls of Terracina (Italy)

Bastion in polygonal work of Roman Republican times, with a subsequent angular spur of reinforcement and the elevations of the late antique and contemporary period. In the wide area of the ancient Latium Vetus - roughly enclosed within the coast and the Apennines between Rome and Terracina, in Central Italy - there are several examples of town's walls and buildings constructed with the spectacular megalithic technique called polygonal, in which enormous blocks are cut in irregular shapes and perfectly fit together without mortar. In Italy all polygonal walls are currently attributed to the Romans, and dated to the first centuries of the Roman republic (V-III century BC), although for most of these constructions no reliable stratigraphy is available.
