Sultanahmet Square

About Sultanahmet Square

Sultanahmet Square is the open public space at the heart of Istanbul's historic peninsula, and for most visitors it's the natural starting point for the old city. The ground it sits on was the ancient Hippodrome, the chariot-racing arena of Byzantine Constantinople, where crowds once packed the stands and the city's political life often spilled into the open. That history is still visible in the monuments spaced along the square: the Obelisk of Theodosius, an Egyptian obelisk brought to the city in the 4th century; the Serpent Column, moved here from Delphi; and the Walled Obelisk, a rougher stone pillar at the far end. The old racing track's shape still roughly defines the layout you walk through today.

What makes the square so useful is everything clustered around it. Hagia Sophia and the Blue Mosque face each other across the gardens, the Basilica Cistern sits a short walk away, and Topkapi Palace and the Grand Bazaar are both within easy reach on foot. This is why so many full-day old-city tours use Sultanahmet as their base, covering the Byzantine and Ottoman sides of Istanbul in one loop without much backtracking. The square itself is free to walk through and open at all hours, with fountains, benches, and tea sellers making it a decent place to rest between sights.

A few practical notes. The Blue Mosque and Hagia Sophia are both active places of worship, so dress modestly and be aware that access can be limited around prayer times. The Basilica Cistern reopened in 2022 after a long restoration and now runs evening sessions as well as daytime ones, so it's worth checking current arrangements before you go. Sultanahmet is well served by the T1 tram, which stops right at the square, and the whole area is walkable, though the streets around it are cobbled and uneven in places.
