The Roman Agora at Athens is located to the north of the Acropolis and to the east of the Ancient Agora.
The original Agora was encroached upon and obstructed by a series of Roman buildings, beginning with the imperial family’s gift to the Athenians of a large odeion (concert hall). The Odeon of Agrippa was built by him in around 15 BC, and measured 51.4 by 43.2 metres, rose several stories in height, and – being sited just north of the Middle Stoa – obstructed the old agora. In return for the odeion, the Athenians built a statue to Agrippa at the site of the previous agora; they based it on a plinth recycled from an earlier statue by covering the old inscription with a new one
The Tower of the Winds or the ( is an octagonal Pentelic marble clocktower in the Roman Agora in Athens that functioned as a horologion or “timepiece”. It is considered the world’s first meteorological station. Unofficially, the monument is also called Aerides, which means Winds.
