“At the heart of Byzantium was its capital, Constantinople, now modern Istanbul. Today it may look like a Turkish city but it contains an old city that was once a huge Roman metropolis and the largest city in Europe for nearly 1,000 years. Even today it has the remains of almost as many Roman buildings as Rome itself – towering walls and aqueducts, huge pillared underground cisterns, and churches that still dominate the modern skyline.”
