The ancient greek amphitheatre of Segesta

Segesta's other main monument, the amphitheatre, stands on the slopes of Monte Barbaro (literally 'Mount Barbarian') at an elevation of 400 meters above sea level. The theatre has 20 tiers of steps which served as seats, divided into 7 sections by aisles that lead to the U-shaped stage area. The diameter of the semi-circular seating area is 63 meters. The seating area is known as the "cavea" and a good part of it was carved out of the solid rock of the mountain. Scholars differ as to when the it was built. Some archeologists believe it was built around the same time as the temple, or maybe some decades earlier, circa 450 BC. The amphitheatre hosts Greek tragedies most Summers, sometimes alternating seasons with the theatre in Taormina.
