The Haghia Sophia (Aya Sofya) is a church dating back to 1228-1263. It houses some very fine frescoes. It is a major sight of the city.

This is in the entrance part with a portico, where the best frescoes are situated. I am pretty sure this is the wedding in Kana, where water was changed into wine. It's a new edit of a slide I scanned again and edited in 2018.
