Ayasofya in Istanbul: a vast dome over changing faiths

Ayasofya in Istanbul spans Christian and Islamic heritage beneath one monumental dome, revealing how this sixth?century structure reshaped the city’s sacred skyline.

Ayasofya in Istanbul is a single vast interior crowned by a monumental dome, a building where Byzantine and Ottoman histories meet in stone, marble and mosaic. Built in the sixth century during the reign of Emperor Justinian I, it has served as cathedral, imperial mosque, museum and mosque again, anchoring the historic peninsula above the Golden Horn.

Mosaics, calligraphy and a layered interior

Inside Ayasofya, Byzantine mosaics and Ottoman calligraphic panels share the same vast space, revealing successive layers of Christian and Islamic art. Many of the mosaics date from the Byzantine centuries and depict emperors, empresses and sacred figures against gold backgrounds, while large roundels bearing the names of Allah, the Prophet Muhammad and early caliphs hang from the upper walls.Byzantine mosaics and calligraphic panels

Marble columns of varying colours and origins line the nave and galleries, supporting arcades beneath the dome and semi?domes. The floor and lower walls carry polished slabs of marble and other stone set in geometric patterns, while upper surfaces reveal patches of painted plaster and mosaic that hint at changes in decoration over the centuries.marble columns and revetment Light enters through tiers of windows at the base of the dome and along the walls, catching gilded surfaces and stone in different ways during the day.
