Sultanahmet Obelisk (The Obelisk of Theodosius) stands as one of Istanbul’s most striking ancient monuments, located at the heart of Sultanahmet Square. Originally erected in Ancient Egypt by Pharaoh Thutmose III in the 15th century BCE, the obelisk was later transported to Constantinople in the 4th century CE by Emperor Theodosius I, as part of his grand urban projects. Carved from red granite, the monument once stood taller, but during its reinstallation, its base was modified. The hieroglyphics inscribed on its surface narrate the victories of the pharaoh, adding to its historical significance. Today, it remains a fascinating relic of both Egyptian and Byzantine history, drawing visitors who marvel at its endurance through millennia.
