Hagia Sophia (Ayasofya), Istanbul, Turkey. Tourism Site Guide and Review
Construction for Hagia Sophia, the Church of Holy Wisdom, started in 532. Amazingly, it took only five years to complete. It replaced two previous versions of the church that had been destroyed. For more than a thousand years, Hagia Sophia was the largest and grandest church in the world. When Sultan Mehmet II converted it into a mosque, the loss devastated Orthodox Christians. Ironically, Hagia Sophia’s design impressed the Ottomans so much that it was copied in other mosques throughout the empire. In 1935, Mustafa Kemal Ataturk, the founder of modern Turkey, declared Hagia Sophia a museum and work started to restore its mosaics. Today, it is mix of both faiths.
