Obelisk of Theodosius

An Egyptian monument at the heart of old Istanbul

In Sultanahmet Square, where visitors walk through the footprint of Constantinople’s ancient Hippodrome, a tall pink-granite shaft rises above the surrounding paving. Known as the Obelisk of Theodosius, it is not a Roman original: it began as an Egyptian monument, travelled across the Mediterranean and was set up here centuries later. Its location places several layers of history in one public space—ancient Egypt, imperial Constantinople and modern Istanbul—without requiring entry to a museum.

The surviving stone was first erected in Egypt by Pharaoh Thutmose III around 1450 BCE, at Karnak, near the Temple of Amun-Re. Istanbul Metropolitan Municipality’s heritage record says it originally stood with a similar obelisk. Hieroglyphs remain visible on its faces. The monument therefore predates both the Roman Empire and the city’s later Byzantine identity by many centuries. Calling it “Theodosius’s obelisk” refers to its later installation in Constantinople, not to its original Egyptian creator or first home.

From Karnak to the Hippodrome

Several Egyptian obelisks were transported to Roman cities, where rulers used them to shape monumental urban settings. The municipal record associates the move of this shaft to the new capital with Constantine the Great, but says its delivery took a long time for reasons that remain unknown. The stone was finally re-erected at the Hippodrome during the reign of Theodosius I in the fourth century CE. The precise sequence between its departure from Egypt and its installation is not fully explained in the accessible official account, so a simple, confident story of the journey would go beyond what that source establishes.

The present shaft is 19.59 metres high. The same municipal record says it is shorter than the original and probably represents about two-thirds of its former height. That distinction matters when looking at the monument: the stone visible today is a surviving section, not necessarily the complete ancient obelisk. Its placement in the Hippodrome made the Egyptian object part of a Roman public arena. The square still invites visitors to read the monument alongside the city’s later history, rather than as an isolated relic with only one cultural identity.

Read the pedestal as well as the shaft

The carved marble base tells a separate chapter. The Istanbul heritage record describes scenes connected with raising the obelisk and with chariot races attended by the emperor. Inscriptions in Ancient Greek and Latin appear on two sides of the main pedestal, while hieroglyphic writing can be seen on the four faces of the upper stone. These surfaces belong to different periods and purposes: the shaft carries Egyptian royal imagery and text, while the base frames its later display in Constantinople.

The base did not always stand fully above ground. Over time, rising ground levels during the Ottoman era buried its lower portion. British researcher C. T. Newton excavated it in April 1857 down to the bottom level. The pedestal has since remained in a square-shaped recess surrounded by iron railings, as described by the municipality. Visitors can look closely from the surrounding public space, but should not cross the barrier or climb onto the historic structure. The reliefs are details to observe from the path, not a surface for touching or posing.

Finding the obelisk and planning a stop

The monument stands in Sultanahmet Meydanı, in Istanbul’s Fatih district, on the site of the former Hippodrome. Türkiye’s official tourism guide presents the square as a broad public park lined with ancient monuments, including the Egyptian obelisk, the Serpent Column and the Walled Obelisk. That setting makes it easy to include the shaft in a walk around Sultanahmet rather than plan a separate museum visit. The historic square is close to the area’s major landmarks, but each monument has a distinct history and should not be mistaken for another.

This is an open-air monument in a public square, not a ticketed interior attraction. The official heritage and tourism pages do not publish a timed-entry system, a separate admission fee or fixed opening hours for the obelisk itself. Access can still be affected by public events, conservation work or security arrangements in the square, so check local notices on the day. Allow time to view both the carved shaft and the reliefs at the base; a quick photograph from across the plaza will miss much of the detail that makes this monument unusual.

The most rewarding visit is a short act of close observation. Notice the hieroglyphs on the granite, then look down to the marble pedestal and its scenes of imperial spectacle. The contrast helps explain how a monument created for an Egyptian setting acquired another public life in Constantinople and survives in Istanbul today. The obelisk does not tell every part of its own journey—some stages remain uncertain—but what is documented is already remarkable: a stone raised at Karnak around 3,400 years ago, re-erected in a Roman hippodrome and still standing in the city’s historic centre.
