The Tower of the Winds, also known as Horologion, is a beautiful, well preserved tower located in the old part of the Roman Agora at the bottom part of the Acropolis. The eight facades have the winds blowing in every direction carved on them. The tower is 12 meters high and 8 in diameter. If you didn't pay the entry fee for the Agora and the other ancient sites, you can still view the Tower from a distance through bars that protect it from vandalism at night. However, it is a very beautiful monument that is worth admiring close-up. The different winds include Boreas, Zephyr, Skiron, and Euros. Each side is embodied by the wind that blows there.
