The ancient Roman Hippodrome of Constantinople stretches between two famous landmarks, the Blue Mosque and the Hagia Sophia. A hippodrome is an arena for sporting and social events. This hippodrome was an upgrade of one built when the city was called Byzantium. A few centuries later, Roman Emperor Constantine made it the capital of the Roman Empire in the east, aka the Byzantine Empire, and the city’s name changed to Constantinople. A millennium or so later, the city’s name changed again.
