What to See at the Roman Agora of Athens
The Tower of the Winds, the Gate of Athena Archegetis, the Roman marketplace, the Vespasianae and the Fethiye Mosque — a concierge guide to the compact square.
The Roman Agora of Athens gathers a remarkable amount of history into one compact square in the heart of Plaka. The must-see monument is the Tower of the Winds, an octagonal marble water clock, sundial and weather vane carved with the eight wind gods. You enter through the monumental Gate of Athena Archegetis, built with the gift of Caesar and Augustus, and can walk the Roman marketplace, see the well-preserved Vespasianae public latrines, and take in the Ottoman Fethiye Mosque within the ruins. This guide walks you through the key monuments and what to prioritise on a visit that most people complete in under an hour.
What are the must-see monuments at the Roman Agora?
The must-see monument at the Roman Agora is, without question, the Tower of the Winds, the octagonal marble tower that stands near the eastern side of the site. An ingenious ancient timepiece and weather station, it once held a water clock, bore sundials on its faces and was topped by a turning bronze weather vane, and each of its eight sides is carved with a relief of one of the eight wind gods, still clearly visible today. Almost complete after two thousand years, it is the emblem of the site and the reason many visitors come. From it, your eye is drawn across the open marketplace to the Gate of Athena Archegetis, the grand Doric gateway on the western side through which the ancient square was entered.
Beyond these two headline monuments, the Roman Agora rewards a slower look at its layered survivals. The lines of column bases and shop foundations around the courtyard trace the colonnades of the Roman marketplace; the Vespasianae, the Roman public latrines, survive in remarkable condition at the north side; and the domed Fethiye Mosque, from the Ottoman period, stands within the ruins as a reminder of the site's long life at the centre of the old town. Our concierge recommendation is to give most of your time to the Tower of the Winds and the Gate of Athena Archegetis, then take in the marketplace, the latrines and the mosque, allowing about forty-five minutes to an hour for the whole compact site.
What is the Tower of the Winds?
The Tower of the Winds is the supreme monument of the Roman Agora and one of the most ingenious structures to survive from the ancient world. Properly the Horologion of Andronikos Kyrrhestes, after the astronomer credited with it, it is an octagonal tower of white marble that functioned as an elaborate public timepiece and weather station for the ancient city. Each of its eight sides faces a compass point and is crowned by a carved relief of the corresponding wind god — figures such as Boreas, the cold north wind, and Zephyros, the gentle west wind — depicted as winged beings bringing the character of their season. This frieze of the winds still runs vividly around the top of the tower and is the detail most visitors remember.
The tower ingeniously combined several instruments. Sundials carved on its outer faces told the time by day, a water clock fed by a stream from the Acropolis kept time when the sun was hidden, and a bronze weather vane, thought to have been in the form of the sea-god Triton, turned on its roof to indicate the wind. Remarkably, it survived almost intact through the centuries, serving later as a Christian building and, under the Ottomans, as a lodge for whirling dervishes. Our concierge recommendation is to walk slowly around all eight sides to find each wind god and to look for the faint lines of the ancient sundials, then step back to appreciate how completely this single monument fused the science, art and daily rhythm of the ancient city.
What is the Gate of Athena Archegetis?
The Gate of Athena Archegetis is the monumental western entrance to the Roman Agora, and the point at which you step from the lanes of Plaka into the ancient marketplace. Built of Pentelic marble in the Doric order, with four tall columns carrying a pediment, it was raised with the funds given by Julius Caesar and Augustus and dedicated to Athena Archegetis, Athena the Leader and guardian of the city. An inscription on its architrave still records this imperial benefaction, a direct link between the stones before you and the Roman leaders who paid for them. Framed against the old-town streets, the gate makes a striking impression and sets the scale of the square beyond.
The gateway also carried the practical business of the marketplace. An inscription associated with it preserves a Roman edict fixing the tax on the sale of oil and the duties of the dealers, a small but vivid window onto the commercial life the agora was built to serve. A second, matching gateway once stood on the eastern side near the Tower of the Winds, so the colonnaded courtyard was entered from both ends. Our concierge recommendation is to pause beneath the Doric columns of the western gate to read its scale and imagine the traders and goods that once passed through, before walking into the marketplace itself — it is one of the most direct transitions anywhere from the living old town to the ancient city at its heart.
What are the marketplace and the Vespasianae?
The heart of the Roman Agora is the marketplace itself, a large rectangular courtyard once surrounded on all sides by colonnaded porticoes that sheltered rows of shops and storerooms. Traders sold their goods in the shade of these stoas while the open central court filled with stalls and customers, and the plan you can read on the ground — the column bases, the shop foundations, the paved court — shows clearly how a Roman commercial agora was arranged. Because the site is compact and mostly level, it is easy to walk the whole square and picture the crowds, the awnings and the cargo that once filled it, with the Tower of the Winds rising at the far end.
One of the most memorable survivals is the Vespasianae, the public latrines of the Roman marketplace, remarkably well preserved at the northern side of the site. A rectangular hall with bench seating arranged around its walls above a drainage channel, it served the crowds who used the agora and is one of the best-surviving Roman public conveniences anywhere — a frank, human detail that brings the everyday life of the ancient city vividly close. Our concierge recommendation is not to overlook it: alongside the grand tower and gate, the latrines are a reminder that the Roman Agora was a working, lived-in marketplace built for the practical needs of a busy city, not only for monuments and display.
What is the Fethiye Mosque, and the later history of the site?
The Fethiye Mosque stands within the Roman Agora on its northern side, the finest reminder that this square was continuously lived in long after antiquity. Built in the Ottoman period on the foundations of an earlier Byzantine church, the mosque — its name means the Mosque of the Conquest — is a handsome domed building that served the Muslim community of Athens when the ancient marketplace lay at the centre of the inhabited old town. For long stretches of the site's history, houses, workshops and religious buildings crowded over and among the ancient ruins, and the mosque is the most complete survivor of that Ottoman Athens.
Carefully restored, the Fethiye Mosque adds a striking counterpoint to the classical monuments around it and is sometimes used for exhibitions on the later history of the site. Together with the Tower of the Winds, which itself served as an Ottoman dervish lodge, it shows how Roman, Byzantine and Ottoman Athens overlapped in this one square across two thousand years. Our concierge recommendation is to take a few minutes at the mosque to appreciate that continuity: within a short walk you move from a Roman gateway and a marble weather station to an Ottoman dome, a compressed history of the city gathered in a single, atmospheric marketplace in the heart of Plaka.
