amphitheater — a large circular or oval building with rows of seats sloping downward toward the center area

a gladiator performer raises his sword triumphantly in the central sandy arena below. Tourists sit scattered throughout the curved rows of stone seats that rise up in tiers around him. The circular stone seating arrangement creates perfect sightlines down toward the performer in the center. Each level of seats sits higher than the one in front, forming a bowl shape. Spectators cheer and point down at the entertaining gladiator show happening below them. Vendors walk up and down the stepped aisles between the tiered seating sections. a large circular building with rows of seats sloping downward toward the center area
