A dome that rewrote architecture, 1,500 years on. Be there before 8am.
Hagia Sophia has been a cathedral, a mosque, a museum and a mosque again over 1,500 years — a dome that rewrote what architecture could do. It's overwhelming, and so are the crowds.
Absolutely — 1,500 years of history in one dome; go before 8am and around prayer times.
It's a ticketed sight — book online in advance to skip the queue.
Be there before 8am or in the evening, because the midday crush and the tourist queue are brutal.
