Ancient Greece's restored Tower of Winds keeps its secrets


It is said to be the world’s first weather station, to date back more than 2,000 years, and to have been used by merchants to tell the time – even in darkness.

The Tower of the Winds, still standing at the foot of Athens’s ancient Acropolis hill despite attempts by Lord Elgin to move it to Britain, has been restored and reopened to the public for the first time in nearly 200 years.

No one knows who funded its lavish construction – the octagonal monument is made almost entirely of Pentelic marble, the same used for the Parthenon and rarely found in buildings other than temples.

At nearly 14 meters (46 feet) tall, it is credited to the architect and astronomer Andronicus of Cyrrhus, but all these years later no one knows exactly how it worked.

“It was, we believe, the world’s first weather station,” Stelios Daskalakis, head of conservation, told Reuters.

“It’s located in the Roman Agora [market place] as it was of great value for the merchants to read the weather and also tell the time their goods would arrive,” he said.

Atop its fully preserved roof, made of 24 marble slabs, rests a Corinthian capital which possibly served as the base of a bronze wind vane in the form of sea god Triton, Daskalakis said.

Beneath it is a frieze of eight Anemoi – wind gods of Greek mythology – each facing a different direction. And beneath that, lines of a sundial.

The greatest mystery remains how the clock worked at night.

Based on the most prominent theory, a hydraulic mechanism powered a water clock device with water flowing from a stream on the Acropolis hill.

“It’s unique in that such an important work was not a temple but had a utilitarian use,” Daskalakis said. “We don’t know who funded it, whether it was private or a high-ranking official.

“The only thing justifying such a high cost is Athens wanting to upgrade the Roman Agora.”
