🏛️ Two monuments, one ticket
The site you'll see on your ticket is officially "Roman Agora," and it has two distinct things to look at:
- The Roman Agora itself — the marketplace built in the 1st century BC under Julius Caesar and Augustus to handle Athens' commercial overflow as the older Greek Agora became increasingly congested with monuments.
- The Tower of the Winds — also known as the Horologion of Andronicus of Cyrrhus — an octagonal marble tower in the Agora's eastern corner that predates the Roman Agora by perhaps a generation.
You enter through the imposing western Gate of Athena Archegetis, a propylon of four Doric columns funded by Julius Caesar around 11 BC, and walk into a wide rectangular courtyard. To your right are the foundations of the colonnaded shops; ahead and to the left, the surviving Tower; behind it, against the Acropolis cliffs, the Ottoman-era Fethiye Mosque (built 1456, after Mehmet II's conquest, on top of an earlier Byzantine basilica).
🌬️ The Tower of the Winds — what to look for
The structure is small — 12 metres tall, 8 metres in diameter — but every surface does something. According to the Greek state record summarised by Greeka, it was built around 50 BC by the astronomer Andronicus of Cyrrhus in fine Pentelic marble. Three things to find as you walk around it:
The eight wind reliefs
Just below the cornice, each of the eight outer walls carries a sculpted figure of a wind deity, pointing in the corresponding direction: Boreas (N, bearded man with a conch), Kaikias (NE, hailstones), Eurus (E, warm wind, a cloak), Apeliotes (SE, fruit and grain), Notus (S, water jug), Lips (SW, ship's stern), Zephyrus (W, flowers), Skiron (NW, fire pot). These are the originals, weathered but legible.
The sundial scratches
Below each wind, look for fine vertical lines incised into the marble — these are the gnomon-line traces of the eight sundials. The bronze pointer that cast the shadow is gone, but the time-grid is still there.
The wind vane (lost)
A bronze Triton with a rod once stood on the conical roof, rotating to point at whichever wind was blowing. Vitruvius, writing in the 1st century BC, describes it; the Tower is one of the few ancient buildings he names directly. The Triton is long gone.
The water clock (also lost)
Inside the Tower, water from the Acropolis spring once drove a sophisticated clepsydra — a klepshydraulic clock — that chimed the hours mechanically. The interior is now a single stone room, but the channels that fed the water clock are visible in the floor.
🏰 The Tower's afterlives
The Tower is one of the few classical buildings in Athens that has been continuously useful for 2,000 years:
- 1st c. BC – 4th c. AD: Public weather and time station for the Roman commercial centre.
- Early Christian period: Adapted as the bell tower of a small church.
- Ottoman era: Used as a tekke, a meeting house for whirling dervishes of the Mevlevi order. The interior plaster from this period was removed in the 19th-century excavations, revealing the marble underneath.
- 1837 onwards: Excavated and conserved by the Archaeological Society. Most recently restored and reopened to interior visits in 2016.
The architectural influence is enormous. As Greeka points out, the Tower was directly copied for the 18th-century Radcliffe Observatory in Oxford, the Temple of the Winds at Mount Stewart in Northern Ireland, and similar weather-science buildings as far away as Sevastopol. Plus essentially every neoclassical wind-vane tower in 19th-century Europe.
📿 The Roman Agora itself
Easier to absorb than the Tower. Three things stand out:
- The Gate of Athena Archegetis (west entrance) — the most photographed feature, with its inscribed dedication to Augustus and the goddess. The four standing Doric columns are intact.
- The market courtyard — paved by Hadrian in the 2nd century AD; the slabs you walk on are largely original.
- The Fethiye Mosque (corner of the site) — a 15th-century Ottoman mosque, restored 2010–2017, occasionally open for temporary exhibitions. The minaret was demolished after independence; the prayer hall, with its reused ancient column drums, survives.

🕒 How long it takes
30–45 minutes
Realistic average. The site is small and most visitors do a single perimeter loop.
1 hour
If you go inside the Tower (worth doing — interior access is included) and study each wind relief in turn.
15 minutes
If you only have a combined ticket and a tight schedule. Walk straight to the Tower, photograph the winds, exit. Even this is worth it.
📸 Photography
The Tower's eight-sided shape is the photographic gift. Best angle: from the south-east corner of the Agora, in late-afternoon light when the wind reliefs catch low sun. Sunset shots from the same corner with the Acropolis cliff rising behind the Tower are the postcard. From outside the site, Aiolou Street (the pedestrian street leading north from the Tower) gives the cleanest "Tower-with-sky" composition.
🚶 What to combine it with
The Roman Agora sits in a tight cluster with three other Hadrianic / Roman-era sites that you can sweep in 90 minutes total:
- Hadrian's Library — 250 metres north on Areos Street.
- Roman Agora & Tower of the Winds — this site.
- Ancient Agora & Temple of Hephaestus — 300 metres west across Plaka, the larger Greek-period equivalent.
- Plaka and Anafiotika — the small white-village neighbourhood of Anafiotika is two minutes south, and a coffee at one of its tavernas is the perfect cap.
🎯 FAQ
Can you go inside the Tower?
Yes — since 2016, the Tower's interior is included with the Roman Agora ticket. Hours sometimes restrict interior access (typically 9:00–14:00) for conservation reasons; check at the gate.
Is it accessible?
The Agora courtyard is mostly flat, with paved sections and gravel. The Tower interior has a small step at the entrance. Manageable for most visitors but not fully wheelchair-friendly.
How does this compare to the Greek (Ancient) Agora?
The Roman Agora is smaller, more focused, and easier to "read" — most visitors prefer it as a 30-minute stop. The Greek Agora is much larger, with the Temple of Hephaestus, the Stoa of Attalos museum, and 30 individual structures spread over hectares. They complement each other; if you have a combined ticket, do both.
