The Roman Agora of Athens — sometimes called the Roman Forum — is the marble marketplace that became the commercial heart of the city in Roman times. It lies in the old district of Plaka, just east of the older Greek Ancient Agora and only a few minutes' walk below the Acropolis, at the very centre of historic Athens. Built with donations from Julius Caesar and the emperor Augustus in the 1st century BC, it shifted the city's trading life from the classical Agora to a grand new colonnaded square, and it remained a bustling commercial and civic space for centuries.
What you walk through today is a compact but remarkable group of monuments. The showpiece is the Tower of the Winds, the octagonal marble Horologion of Andronikos Kyrrhestes, which served the ancient city as a water clock, sundial and weather vane, its eight faces carved with reliefs of the eight wind gods — one of the best-preserved and most ingenious structures to survive from antiquity. You enter through the monumental Gate of Athena Archegetis, the Doric west propylon built with Caesar's and Augustus's gift, and can see the Vespasianae, the well-preserved Roman public latrines, and the later Fethiye Mosque, raised within the site during the Ottoman period. Together they trace the long life of this one square, from Roman marketplace to Ottoman town.
The Roman Agora is one of the easiest of all Athens's ancient sites to reach: it stands in the pedestrian heart of Plaka and Monastiraki, moments from the metro and from the Acropolis and the Ancient Agora, so most visitors fold it naturally into a walk between the great monuments. The ground is open and largely unshaded, so early-morning or late-afternoon hourly slots are far kinder than the middle of the day. Because entry is timed by the hour, we handle the ticketing in your own language and reserve the slot you want, so you can give your energy to the ruins instead of the queue.
