Around 3,400 years ago, Theodosius Thutmose III built the Temple of Karnak, just outside of Luxor. Around a thousand years later, Theodosius from Constantinople brought an obelisk from the Temple of Karnak home and planted it near the race track.
He had to cut it into three pieces. The bottom two pieces seem to have been misplaced, or maybe broken. This is the top piece, still at the Hippodrome in Istanbul. Spires from the Blue Mosque are in the background.
