Walk across the park from Hagia Sophia and you find yourself at the Hippodrome - the heart of Constantinople’s social and sporting activities.  Built as a venue to house chariot races, it had the capacity to hold a hundred thousand spectators. Sadly, all that now remains of the Hippodrome are the three pillars that used to be part of its ‘spina’ - the central line around which chariots raced. #Constantinople #Hippodrome #architecture #history
