The lofty minarets of the Hagia Sophia stand over the skyline of Istanbul, Turkey. The magnificent stone basilica has been a fixture of the ancient city for 1,500 years—with frequent additions and renovations.
The spiritual structure has survived empires and transitioned religions. What began as an early Christian basilica eventually became a mosque, then a museum, and is now once more a mosque.
An architectural wonder, the Hagia Sophia (meaning “holy wisdom” in Greek) has a fascinating history and is a favorite attraction for tourists and the faithful. The building has seen crusades, world wars, and vast political shifts, but its legacy is central to both the history of Turkey and the world.
Read on for the history of the Hagia Sophia, a fascinating piece of sacred architecture.
As with many great cathedrals and basilicas, the Hagia Sophia stands on a site that is purported to have long been a place of religious buildings.
It is believed that a Roman pagan temple once stood where the modern building lies. Under the Roman Empire, the important ancient city on the Bosporus was known as Byzantium until the reign of Emperor Constantine I. The first Christian emperor, he moved his capitol from Rome to Byzantium in 324 CE. The city was then renamed Constantinople. This monumental shift in Roman religious policy and the geographic center of power established Constantinople as an important Christian site. The Bishop of Constantinople became second only to that of Rome in power and prestige.
The first Christian church on the site of the Hagia Sophia is thought to have been completed by Constantine’s son the Emperor Constantius II in 360 CE, although its construction may have been ordered by Constantine himself upon his establishment in the new capitol. The Roman emperors who followed continued to make additions and repairs to what was called “the Great Church.” Excavated remains of the ancient church as it stood in the 5th-century shows complex stonework, including vaulted ceilings and friezes depicting early Christian symbolism. The ancient church was destroyed by fire in 532 CE during the Nika Revolt—a politically motivated violent rampage by upset citizens who took issue with many of the advisors and policies of Emperor Justinian I.
Under Control of Justinian the Great
Despite facing a huge revolt, the emperor has been remembered by the moniker Justinian the Great. Ruling from 527 to 565 CE, the emperor controlled only the eastern half of what was once the Mediterranean-encompassing Roman Empire. The western half, including Rome itself, had weakened internally. Its rulership politically disintegrated under pressure from “barbarians” such as the Germanic Goths. By 476 CE the western empire was defunct. The eastern half became known as the Eastern Roman Empire or the Byzantine Empire. Justinian I presided over a period of military expansion and legal reform. He is famous for his Code of Justinian, which revamped Roman civil law to create a uniform and exclusive legal system.
Among his major legacies is the present-day Hagia Sophia. After the Nika Revolt destroyed the Great Church, Justinian almost immediately
Despite the mathematic prowess of the designers, the new building could not support the weight of its own dome during two earthquakes in the 550s. A new ribbed dome was constructed which was actually taller but better supported by pendentives (corner supports in the square space underneath). The opulent interior of the church was decorated further by Justin II—Justinian’s heir—who added gold mosaics. An “Imperial Door” was reserved for the emperor’s personal use.
Over the almost 900 years the building remained in Byzantine hands, the successive emperors added new features to the church. Between the 10th and 12th centuries, many mosaics were added or altered. They depict figures such as the Byzantine Emperors, Constantine the Great (who received sainthood in the Eastern church), the Virgin Mary, and Christ. Other additions had pagan origins.
Throughout the Byzantine period, the Hagia Sophia required many repairs due to age and other damage from earthquakes and fires. In 1054, the

Claimed by Ottoman Rule
The events of the 13th century permanently weakened the Byzantine Empire. In contrast, the Turkish cultures to the east of Byzantine lands were growing in power.
Taking its name from the leader Osman I, the Ottoman Empire pushed into the Balkans and steadily gained military might. Sultan Mehmed II captured Constantinople in 1453, effectively taking the last crown jewel of the old Byzantine Empire. During this conquest, the already old building was further damaged and looted. However, its beauty seemed to have struck the Sultan, who decided to convert the church to a mosque.
Religiously, this conversion meant a reading of the shahada (a declaration of faith) and the holding of Friday prayer at the Aya Sofya (Hagia Sophia in Turkish). Architecturally, the change in faiths dictated several new additions. A mihrab facing the direction of Mecca replaced the Christian altar, and a minbar (a pulpit with stairs for sermons) was also added. A minaret was also added, from which the call to prayer sounded.
The Ottoman rulers continued to repair and alter the building much as their Byzantine predecessors did. The minarets seen today were added in the 15th and 16th centuries. The 16th-century ruler Suleiman the Magnificent plastered over the Byzantine mosaics;
Becoming a Modern Museum
After World War I, the Ottoman Empire ceased to exist as a political entity, and the Republic of Turkey was officially recognized in 1923. Constantinople became the city of Istanbul. In 1934, under President Kemal Atatürk, the Hagia Sophia was secularized. The next year, the building was turned into a museum and the once-covered mosaics and original ancient floor were unearthed.
Throughout most of the 20th century, frequent repairs were necessary. Falling within the designated UNESCO World Heritage Site known as the “Historic Areas of Istanbul,” the building has been the object of frequent conservation. Now, over three million people a year visit the famous site.
Back to Worship Space
As a space held sacred to both Orthodox Christians and Muslims, many believers have a vested interest in the use of the Hagia Sophia as a place of worship. In the past ten years, calls to reconvert the secular building back into a mosque have grown.
In July of 2020, the museum was officially converted back into a mosque under the leadership of President Recep Tayyip Erdogan. The move has ignited much
The Hagia Sophia’s return to being a place of worship is one more chapter in the long, captivating history of this sacred site; being at the center of national and geopolitical events is nothing new for this magnificent structure.
