The Roman Agora is located in Plaka, the picturesque neighborhood just below the Acropolis. It was developed between 19 and 11 BC and gradually flourished due to Roman emperors' donations, euch as Julius Caesar and Hadrian. It was the commercial center of Athens in Roman times.

Within the area of ​​the Roman Agora is one of the most distinctive buildings of ancient Athens, the Winds or more correctly the Clock Tower of the Winds. It is a marble building in shape of an octagon, with 12 m height, that was constructed by the astronomer Andronikos from Kyrros in the mid 1st century BC. In antiquity it functioned as a solar and hydraulic clock but also as a meteorological station, maybe the oldest in the world. The name Winds was given to the building by the inhabitants of Athens, because of the winds that were engraved and inscribed with their names in each of the eight sides of the building. At the top of the building there was once a vane and depending on its position, market traders and passers-by always knew what kind of wind was blowing.
