The commercial heart of Roman Athens

The Roman Agora of Athens was born from the changing fortunes of the city under Rome. By the 1st century BC classical Athens had lost its political independence but remained a revered centre of philosophy, art and prestige, and Rome's leaders courted it with benefactions. It was with donations from Julius Caesar, and then the emperor Augustus, that the Athenians laid out a grand new marketplace to the east of their ancient Greek Agora — a large rectangular courtyard surrounded by colonnades, shops and storerooms, entered through monumental gateways. As the new square took over the city's commercial life, the older Agora to the west increasingly became a place of administration, memory and philosophy, while the buying and selling shifted here.

For centuries this was the busy trading heart of Athens, its colonnades sheltering merchants and its courtyard filled with stalls. The square kept evolving long after antiquity: in the Byzantine and especially the Ottoman periods it lay at the centre of the inhabited old town, and houses, workshops, a mosque and other buildings rose over and among the ancient remains. Excavation from the 19th and 20th centuries cleared much of the classical marketplace while leaving standing some of the most striking survivals of each age. What you walk through today is therefore not a single moment frozen in time but a compressed history of Athens — Roman marketplace, Byzantine and Ottoman town — gathered into one atmospheric square in the middle of Plaka.

The Tower of the Winds

The undoubted star of the Roman Agora is the Tower of the Winds, one of the most ingenious and best-preserved structures to come down to us from the ancient world. Properly the Horologion of Andronikos Kyrrhestes, after the astronomer said to have built it, it is an octagonal tower of white marble that stood at the eastern edge of the marketplace and functioned as an elaborate public timepiece and weather station. Each of its eight sides faces a point of the compass and is crowned with a carved relief of the corresponding wind god — Boreas the cold north wind, Zephyros the gentle west wind, and the others — depicted as winged figures bearing the gifts or hardships of their season, a frieze that still runs vividly around the top of the tower.

The tower packed several instruments into one elegant structure. Sundials were carved on its outer faces to tell the time by day, a water clock driven by a stream from the Acropolis kept time when the sun did not shine, and a bronze weather vane in the form of the sea-god Triton is thought to have turned on its roof, pointing to the wind blowing at any moment. Remarkably, the tower survived almost intact through the centuries, serving in turn as a place of Christian worship and, under the Ottomans, as a tekke used by whirling dervishes. Standing before it today, you can still read the wind gods overhead and trace the lines of the ancient sundials — a rare chance to see the science, art and daily rhythm of the ancient city fused in a single, complete monument.

The Gate of Athena Archegetis

You enter the Roman Agora much as ancient visitors did, through the Gate of Athena Archegetis, the monumental western propylon that formed the marketplace's principal entrance. Built of Pentelic marble in the Doric order, with four tall columns supporting a pediment, it was raised with the funds given by Julius Caesar and Augustus and dedicated to Athena Archegetis — Athena the Leader, the city's guardian. An inscription on the architrave still records the imperial benefaction, a direct link between the stones in front of you and the Roman leaders who paid for them. Framed against the streets of Plaka, the gate makes a striking first impression and sets the scale of the square beyond.

The gateway did more than mark an entrance. Roman authorities used such public spaces to display civic rules, and an inscription associated with the gate preserves an edict fixing the tax on the sale of oil and the duties of dealers — a small but telling window onto the commercial life the marketplace was built to serve. A matching gateway once stood on the eastern side, near the Tower of the Winds, so that the colonnaded courtyard was entered from both ends. Passing beneath the Doric columns of the western gate, you step from the medieval lanes of Plaka straight into the Roman city's marketplace, an unusually vivid transition from the living old town to the ancient square at its heart.

The marketplace and the Vespasianae

Beyond the gate opens the marketplace itself, a large rectangular courtyard that was once surrounded on all sides by colonnaded porticoes, or stoas, sheltering rows of shops and storerooms. Traders sold their goods in the shade of these colonnades while the open central court bustled with stalls and customers, and the plan you can trace on the ground — the lines of column bases, the foundations of the shops, the paved court — gives a clear sense of how a Roman commercial agora was organised. Because the site is compact and largely at one 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 unexpected survivals here 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 four walls above a drainage channel, it served the crowds who used the agora and is one of the best-surviving examples of a Roman public convenience anywhere — a frank and human reminder that these grand civic spaces were built for the practical needs of everyday life as much as for commerce and display. Interpretive signs help you read these features, but much of the pleasure of the Roman Agora lies simply in wandering a real Roman marketplace, tucked between the cafés and lanes of modern Plaka.

The Fethiye Mosque and the Ottoman city

The Roman Agora is not only a Roman site: it carries the layers of every age that followed, and the most visible of these is the Fethiye Mosque, which stands within the square on its northern side. 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 like this crowded over and among the ancient ruins, and the mosque is the finest survivor of that Ottoman Athens.

Carefully restored, the Fethiye Mosque adds a striking counterpoint to the classical monuments around it, and it is sometimes used for exhibitions that illuminate the later history of the site. Together with the Tower of the Winds — which itself served as an Ottoman dervish lodge — the mosque reminds visitors that this one square was continuously lived in for two thousand years, not simply an ancient ruin but a place where Roman, Byzantine and Ottoman Athens overlapped. Our concierge recommendation is to take a few minutes at the mosque to appreciate this long continuity: within a short walk you can move from a Roman gateway and a marble weather station to an Ottoman dome, all in a marketplace that never really stopped being the heart of old Athens.

Getting there and visiting

The Roman Agora is one of the easiest of all Athens's ancient sites to reach, because it lies right in the pedestrian heart of the old town. It stands in Plaka, just east of the Greek Ancient Agora and only a few minutes' walk below the Acropolis, so most visitors come to it on foot as part of a stroll between the great monuments. The nearest metro station is Monastiraki, on Lines 1 and 3, about a five-minute walk through the lanes; Acropoli, on Line 2, is also close. The little entrance sits at the corner of Polygnotou and Aiolou streets, and it is worth noting that the Roman Agora is a separate site and ticket from the older Ancient Agora nearby — the two are easy to confuse but stand a short walk apart. Entry is now by timed hourly slot, so arrive within the hour shown on your ticket.

The Roman Agora is a compact, open-air site, and a visit is short but rewarding — most people spend around forty-five minutes to an hour taking in the marketplace, the Tower of the Winds, the Gate of Athena Archegetis, the Vespasianae and the Fethiye Mosque. The ground is a mix of gravel, ancient paving and low ruins with a few steps, and there is limited shade across the open square, so sturdy shoes, a hat, sunscreen and water are advisable in the Athenian summer. Because it is so central and so compact, the Roman Agora pairs perfectly with the Acropolis and the neighbouring Ancient Agora for a fuller morning in classical Athens; booking an early or late hourly slot gives you the coolest air, the softest light and the calmest walk among the monuments, before the Plaka crowds thicken in the middle of the day.
