The Tower of the Winds

Selected for Google Maps and Google Earth

The Tower of the Winds, also called horologion (timepiece), is an octagonal Pentelic marble clocktower on the Roman agora in Athens. The structure features a combination of sundials, a water clock and a wind vane. It was supposedly built by Andronicus of Cyrrhus around 50 BC, but according to other sources might have been constructed in the 2nd century BC before the rest of the forum.

The 12-metre-tall structure has a diameter of about 8 metres and was topped in antiquity by a weathervane-like Triton that indicated the wind direction Below the frieze depicting the eight wind deities — Boreas (N), Kaikias (NE), Eurus (E), Apeliotes (SE), Notus (S), Livas (SW), Zephyrus (W), and Skiron (NW) — there are eight sundials. In its interior, there was a water clock (or clepsydra), driven by water coming down from the Acropolis. Recent research has shown that the considerable height of the tower was motivated by the intention to place the sundials and the wind-vane at a visible height on the Agora, making it effectively an early example of a clocktower. According to the testimony of Vitruvius and Varro, Andronicus of Cyrrhus designed the structure.
