A must visit. No words to describe how beautiful it is and how much history lies in this one place. One tip: the line for it can get realllly long, your best bet is to go early in the morning approx. 9am and the lines are MUCH shorter and there would be less people inside so better view of everything....

It’s one of the nicest cathedrals in Europe with so much history and events. You have to visit this place first thing in the morning when not too many people there, and easy to buy daily tickets.

This is the Must see place in Istanbul ! The History is just Incredible ! Go Early and if you plan to visit loads of Museums in Istanbul then buy the museum card and go straight to special line , smaller line ?

Great place with a lot of history, pagan, christianity and islam. Very impressive building with respect to its age. This is a most for everyone who visits Istanbul.
