Description
Hagia Sophia Grand Mosque is located in Sultanahmet Square in Istanbul’s historic Fatih district, neighbouring the Blue Mosque and Topkapı Palace. Originally built as a Byzantine cathedral under Emperor Justinian in 537 CE, it served as the world’s largest church for centuries. After the Ottoman conquest of Constantinople in 1453, it was transformed into a mosque with the addition of minarets and Islamic features. It became a museum in 1935 and was converted back into a functioning mosque in July 2020.
The architecture fuses Byzantine and Ottoman elements to stunning effect. Its massive central dome (31 m diameter) appears to float above the main hall, supported by pendentives and arches pioneered by architects Anthemius of Tralles and Isidore of Miletus. The interior is richly adorned with marble columns, vast mosaics, fresco fragments of imperial and religious iconography, and Islamic calligraphy panels. While serving as a mosque, prayer sessions continue uninterrupted, and key mosaics are shielded during worship.
Hagia Sophia remains open daily for visitors—typically from around 08:00 to 19:30 (last entry 18:30)—but closes to tourists during Friday midday prayers (approx. 12:30–14:30). Non-Muslim visitors must purchase a ticket valid for access to the visitor gallery and upper levels, while Muslims may enter the prayer area during worship free of charge. Modest dress is required, women must cover their heads, and shoes are removed before entry; scarves are available at the entrance. The site is wheelchair accessible at ground level, though upper galleries may require some assistance. Restoration is underway to strengthen the domes and underground structures against earthquakes—visitors can expect scaffolding but uninterrupted access.
