Hagia Sophia (Ayasofya) stands in Sultanahmet, Istanbul. Built as a cathedral in the 6th century, later a mosque, then a museum, it is again a working mosque. The prayer hall follows mosque rules. An upper gallery visitor route has been ticketed at times; confirm the current split on official Turkish pages before you go.
Justinian's 6th-century dome is the building's reason for fame. Restoration scaffolding can appear; the building typically stays open around the works.
Cover shoulders and knees. Women should bring a headscarf. Shoes come off on carpets. Staff may pause visits around the five daily prayers, longer at Friday midday.
The Blue Mosque, Topkapi Palace, and the Hippodrome are on the same peninsula. They are separate tickets and queues.
Treat Hagia Sophia as a mosque first. Visitor products (including any upper-gallery ticket) change. Confirm on official culture or mosque pages, not on reseller blogs.
Byzantine mosaics, Ottoman calligraphy, and a Christian plan reused as a mosque are the point of the visit.
The Blue Mosque is a later building across the square. See both if you have time; they are not the same interior.
Short closures around namaz are normal. Friday noon is the longest pause for tourists.
Is Hagia Sophia a museum or a mosque?
It is a working mosque again (since 2020). Dress and prayer-time rules apply.
Do visitors pay?
The prayer hall is generally treated as a mosque (free, with etiquette). Upper-gallery or museum-style tickets have been sold at times. Confirm the current official product rather than an old blog price.
What should I wear?
Shoulders and knees covered for everyone. Headscarf for women. Easy-off shoes.
Which tram?
T1 Sultanahmet is the usual stop.
Hagia Sophia was completed in 537 under Justinian I as the Great Church of Constantinople. It became a mosque after 1453, a museum in 1935, and a mosque again in 2020.
Because its legal status and visitor route have changed more than once, ignore outdated 'museum ticket' advice. Follow on-site signs and current official hours.
