A bird's-eye view of Hagia Sophia on the shore of the Bosporus, Istanbul.
The present-day Hagia Sophia in Istanbul was completed in 537 CE.123
Commissioned by the Byzantine Emperor Justinian I following the destruction of a previous church during the Nika insurrection in 532 CE, the structure was built in the remarkably short period of approximately six yearsâspecifically five years, 10 months, and four daysâunder the direction of architects Anthemius of Tralles and Isidorus of Miletus.123
