I didn't like it very much. the ticket is 15 TL. it can talk about 30 mins. I don't suggest it for visiting

This is a very large monument underground just next to Ayia Sophia. There is little light inside and they do not allow visitors to take a camera 🎥 tripod inside so you have to count on your steady hands! Really worthwhile a visit -
