The central square has two mosques (one small), a post office, an underground shopping area, a very old and large hamam, and provides a good view of the castle. It also has an artificial palm that will light up at dawn in a weird red. In Turhal I saw a green one. Soon every town will have one. By then they should be taken down again.

This is the larger of the two mosques I mentioned, quite good, but I think the Hatuniye is a bit better. Compare the decoration at their entrances.
