The remarkable Tower of the Winds, located within the ruins of the Roman Agora, was built from marble in the 2nd century. It served as a combined water clock and weather vane.
The name, Tower of the Winds, comes from the external friezes, that personify the eight winds. The structure is well preserved. With a diameter of 26ft and standing just over 40 ft tall, the Greeks today simply call it the “the winds.”
In the middle ages, it was thought to be the prison of Socrates. A legend that has stuck with structure despite it being built hundreds of years later.
Not much remains of the original water clock, except a complex system of pipes, and a circular channel for water cut into the floor that is visible inside the tower.
