This octagonal, 42 foot marble tower along the Roman Agora will catch your eye. The Tower of the Winds was built in 50 BC by Macedonian astronomer Andronicus of Cyrrhus. This was designed as a horologium (sundial) for telling time. The carved reliefs on top represent the eight gods of the wind. The one in the center is Zephyrus. He was the god of the west wind and provider of light breezes during spring and summer.
