Amazing place. Its a must. Better ig you visit with tour guide, since you enter really fast. Did not like that some parts were in maintainance so did not have the chance to see it all.

if you want to see a true historical place in Europe visit Hagia Sophia! Great atmosphere! I liked the aura of the place and the great wall paintings.

Nearly bought tears to my eyes it was so lovely. Look online and try and get the three day museum pass to bypass the horrendous queues

This was a mix of church, mosque and musuem. The history of the place was fascinating and would recommend either a guide or buy the headphones in order to let you know exactly what it is you are looking at. The huge doors on entering are not normally noticed but they are worth a look.

One of the greatest edifices on Earth. Enough said. Buy your Museum Pass to the right of the entrance, then head straight for the entrance. Do NOT make the mistake of becoming entangled in the massive tour group lines.

The Sophia attracts big crowds and for good reason - it is a must-see attraction that is full of awesome sights and lots of history to take in. The audio tour was very informative, if a little jumbled in it's narrative. The tour books recommend 90 mins for this place, we spent 3 hours wandering around learning about it all.... More

Brought me to tears, the history, the architecture. The sophistication of the people of the day. It was a must see for all.

We spent around 3 hours on a rainy day, and it was crowded. After hearing a lot and seeing Hagia Sophia in practically every Istanbul brochure, the structure was super impressive. Its multi layered design speaks volumes of the history it has been a witness to. A must see and ensure you have a good guide or an audio guide... More

It was under renovation and it was way too crowded when we visited, but still a must see if it is your first visit to Istanbul.
