The Tower of the Winds, built under Julius Caesar, owes its name to the 8 winged characters, symbolising the dominant winds of Athens, carved on its eight sides. Note Boreus, the cold wind, in the shape of a bearded man preparing to blow into a conch, and the gentle Zephyr, letting flowers fall from his cloak. It also housed a famous hydraulic clock. Converted into a chapel in the 6C, under the Turks it became a monastery for Muslim holy men. In the 18C it was believed to be Socrates's tomb!
