I was in Constantinople (Istanbul) recently for a consultation and was able to squeeze in a bit of sight-seeing. This was fortunate as I had never been to that city before (excepting the airport, which does not really count). Here are a few pictures of the Hagia Sophia.
You can find some more pictures of the Hagia Sophia at my Flickr page. Just click HERE.
