The town of Segni is surrounded by a wide, perfectly preserved city wall, which takes the name of cyclopean walls due to the imposing mass of its boulders. The date of their construction is unknown, but dates back to the pre-Roman period, before the 4th century BC. and generally they date back to the seventh century BC.

 According to legend, the walls are called “ciclopiche” because they were built by the Cyclops or by the Pelasgians, ancient inhabitants of Greece where similar walls are found in Mycenae, Tiryns and Argo. But similar walls are also found in Peru, on Easter Island or even in Australia.

The name ‘polygonal’ instead derives from their shape: not rectangular but they have a high number of shapes that make sure that each boulder fits perfectly with its neighbour.

The polygonal walls of Segni are interspersed by two large gates, Porta Saracena and Porta Foca, and by minor gates.

The outer walls, in the most part seen from a panoramic path, that leads to a high part of the town where there are the remains of the ancient Acropolis and where there is the church of San Pietro which was built on part of the megalithic walls of the acropolis.
