Official website
Where to find it
The Turkish Ministry of Culture and Tourism maintains the official Hagia Sophia information page at muze.gen.tr/muze-detay/ayasofya. The mosque itself is administered by the Diyanet (Turkish Directorate of Religious Affairs); the upper-gallery Hagia Sophia Experience Museum has its own ticketing portal.
What the official site offers
Authoritative information on opening hours, prayer-time closures, the architectural history of the building, current restoration projects on the dome and apse, and contact details for school visits, research access and press requests. The Ministry portal is the source of truth for any administrative or institutional question.
How this site differs
This site exists to make booking faster, with a clearer mobile experience, in more languages and with flexible cancellation up to 24 hours before your slot. Tickets here include the same upper-gallery admission as those bought direct. For institutional questions, mosque etiquette guidelines, or research access, use the official site.
