Ayasofya in Istanbul, known in English as Hagia Sophia, gathers centuries of faith and power beneath a single vast dome. Built as the principal church of Constantinople and later transformed into a mosque and then a museum, it now stands again as a functioning mosque within the historic district of Fatih. The structure in its present form was completed in the sixth century under Emperor Justinian I, and its scale and engineering make it a central monument of Byzantine architecture.
Ayasofya’s sixth-century basilica and its great dome

From the floor of the prayer hall or the upper galleries, the transition from the heavy masonry supports to the curving dome is marked by tiers of windows at the base of the canopy and by arcades that open above the aisles. The dome itself has been rebuilt in the sixth century after earthquake damage, but it retains the essential proportions that made Ayasofya one of the largest covered interiors of its time.principally the third monument Marble revetments, columns brought from earlier sites and richly worked capitals form vertical bands along the walls, while broad expanses of plaster carry traces of Christian imagery beneath Ottoman inscriptions.
From imperial church to Ottoman mosque and museum
Ayasofya’s story is written in its successive functions. The first church on this site was dedicated in 360 during the reign of Constantius II, son of Constantine, and served as the cathedral of Constantinople.dedicated in 360 That early building, and its fifth-century successor, did not survive riots and fires, and Justinian’s sixth-century project replaced them with the masonry mass seen today.sixth-century project For nearly a millennium after 537, Ayasofya functioned as the principal church of the Byzantine capital, with a brief period under Latin rulers in the thirteenth century when a Western hierarchy occupied the building.Latin rulers in the thirteenth century
