Hagia Sophia Grand Mosque -- A Masterpiece of Byzantine & Ottoman Heritage

Overview: Hagia Sophia Grand Mosque, built in 537 AD, stands as one of the world's most remarkable architectural and cultural landmarks. For nearly a thousand years, it was the largest cathedral in the world. It has served as an Orthodox cathedral, a Roman Catholic cathedral, an imperial mosque, a museum, and now a mosque once again. Its massive dome, stunning mosaics, and blend of Christian and Islamic elements make it a must-visit destination in Istanbul.
