Entry fee for Hagia Sophia

Yes, I can confirm 25 euro entry. Second floor access. I was there in October.

Yes, we were there in August, the tickets were 25 euro. Non Muslims are restricted to the second floor, which wasn't as big of a deal as I thought it would be. Highly, highly, HIGHLY, recommend getting there at least 15 minutes before opening to get in line. At opening, go in and do your photographing and enjoy the views, and then go back when its busier to listen to the audio.

The entry fees for several government-operated sites have increased substantially since I was in the city in September/October 2024. Don't trust any fee-related information you find in a printed guidebook, and keep in mind that stuff posted on the internet tends to live on forever.

This is the official website for the Hagia Sophia mosque which includes hours and links to official online ticket seller https://muze.gen.tr/muze-detay/ayasofya

Opening hours, Tickets Hagia Sophia is open to visitors every day,
opening hours from 09:00 a.m. to 7:30 p.m. in 2024. Visiting area of
the mosque is closed to visitors between 12:30-14:30 due to Friday
Prayers. Admission tickets can be purchased from the ticket booth and
online (Skip-the-Line) through official seller DEM MUSEUMS with below
link. There are no Museum Passes available for visiting the Hagia
Sophia.

It is currently 25 euro to visit the second floor, but that could change at any time so confirm just prior to your visit. I went there before they closed off the first floor access, so one thing to double check is whether the mosque dress code (head coverings for women, modest clothing) is required upstairs (perhaps someone who has visited recently can weigh in).

BTW, there is also a Hagia Sophia history museum, which is not the same thing (but is sometimes covered by museum passes).

FYI. Haggia Sophia history museum is not covered by museum pass. Neither are Basilica Cisterns.

Last week when I went there it was 25 € and they also accept Turkish lira
