Hagia Sophia

About Hagia Sophia

Hagia Sophia was built in the 530s under the Byzantine emperor Justinian, and for nearly a thousand years it was the largest cathedral in the Christian world. Its enormous central dome, which seems to float over the main space with almost no visible support, was an engineering leap for its time and still holds up as the building's defining feature. After the Ottoman conquest in 1453 it became a mosque, gaining minarets, mihrab, and the huge round calligraphy panels that now hang alongside the surviving Byzantine gold mosaics. For a stretch of the 20th century it served as a museum. Since 2020 it has been a working mosque again, so its current status is religious, not a museum, even though the layered history is exactly what most people come to see.

Because it's an active place of worship, tourist visits and prayer are handled separately. Since early 2024, visitors touring the building generally enter through the upper gallery floor, while the ground-level worship area is kept for those praying. That gallery route is where you get the closest look at the mosaics and a good vantage over the interior. Access can be limited around the five daily prayer times, and a modest dress code applies: shoulders and knees covered, and a head covering for women. Scarves are usually available at the entrance if you don't bring one. Tourist entry is a separate, paid arrangement, so it's worth checking current visiting arrangements before you go, since the rules here have changed more than once in recent years.

Hagia Sophia sits right on Sultanahmet Square, directly across from the Blue Mosque and a short walk from the Basilica Cistern and Topkapi Palace, which makes it easy to fold into a single day in the old city. Most people spend under an hour inside, though it's the kind of building that rewards standing still and looking up for a while. Lines can be long in peak season, so an advance or skip-the-line ticket saves time at midday.
