Beautiful church, finest frescoes and mosaics preserved anywhere! It is a cab ride away from Sultanahmet, where we stayed but worth the trip. Combine it with a lunch stop at Asitane, the restaurant next door which serves only food from recipes of the Ottoman Palaces. Amazing place.

Not on the tramway but so worth seeing, this small Byzantine church has the most amazing mosaics. Take a taxi and spend an hour here!

took us a bit to get there... tram metro and then a walk...but the small understated church was quite lovely... a little hard to find...plan ahead

If you liked Hagia Sophia mosaics, you MUST go to Kariye Museum. The history of Jesus and Maria told by mosaics in the charming interior of the building.

When you hear Istanbul, you don't assume Kariye museum but it was one of our favorite places there. The pictures, the history, everything was fantastic

If you are astounded by mosaics, then you will not want to miss this church. Built as a Greek church and later used as a mosque, it is much to the credit of the Muslims that they left these intact, as the representation of people or animals is forbidden by the Sunni Muslim as a distraction from prayer.

A beautiful church well worth visiting. Amazing frescos and mosaics which were instantly recognisable. There were four of us and we took a cab there as it was raining but it was worth the effort. A stunning little gem although a bit crowded. .

A visit to the lovely mosaics at this old Church fits in well with a visit to the Eyup Sultan Mosque, the old walls and other sites in the Western area. Go there by ferry - it's really easy.

It's out of center, but defintely worth the trip. We took a taxi who got us there, there are also taxis waiting there to get you back. Paid 25TL from centre to there. Confirms other reviews, really nice mosaic, but very crowded. Use of tripod is forbidden (as in the other major locations in Istanbul), as well as flashing.
