The Ancient Theater of Side, located in Antalya Province, is one of Turkey’s largest and most remarkable Roman theaters. Built in the 2nd century AD, it reflects the grandeur of Roman architecture with a seating capacity of 15,000 to 20,000 spectators. The structure features elaborate stage decorations, monumental arches, and a distinctive design adapted to the flat terrain, unlike traditional hillside theaters. This site remains a vibrant reminder of Side’s historical prominence as a cultural and trading hub.
