Men waves flags as people gather on July 24, 2020 outside Hagia Sophia in Istanbul to attend the Friday prayer, the first muslim prayer held at the landmark since it was reconverted to a mosque despite international condemnation. - A top Turkish court revoked the sixth-century monument's status as a museum on July 10 and Turkish President then ordered the building to reopen for Muslim worship. The UNESCO World Heritage site in historic Istanbul was first built as a cathedral in the Christian Byzantine Empire but was converted into a mosque after the Ottoman conquest of Constantinople in 1453.
