The Tower of the Winds, also known as the Horologion of Andronikos Kyrrhestes, is an octagonal Pentelic marble clocktower in the Roman Agora in Athens that functioned as a horologion ("timepiece"). It is considered to be the world's first meteorological station, featuring a combination of sundials, a water clock, and a wind vane. The monument got its name from the eight reliefs representing eight wind deities as winged figures. Pictured here, from left to right, are Kaikias (North-West), Boreas (North), and Skiron (North-West).

Under Ottoman rule, sufis (or whirling dervishes) used the Tower of the Winds as a place of worship - a use that is believed to have deterred Lord Elgin from removing it to England along with the Parthenon marbles in the early part of the nineteenth century.
