Istanbul's historic areas encompass one of the world's most extraordinary concentrations of monuments, spanning the Byzantine and Ottoman empires and inscribed on the UNESCO World Heritage List in 1985. Set on the peninsula where the Golden Horn meets the Sea of Marmara, the protected zones bring together the archaeological park of the ancient city, the Süleymaniye quarter, the Zeyrek district and the great land walls raised under Theodosius II. This first installment explores the sacred sites that have shaped the city's spiritual identity across centuries of imperial history, following buildings that have served successive faiths and observing how a living metropolis continues to inhabit its own monumental past.
