This is a modern mosque, called the Sabancı Merkez Cami (SabancSabancı is the name of an industrialist who financed it). When I first visited the city in 1992 they were building it. Some nine years later I had the pleasure of attending a prayer service on a Friday, with thousands of people in a huge, bright space with gorgeous domes, in the classical style, but with marble that was so white as one rarely sees it.

I took a better look at it in 2005, and saw that it lacks the majesty of, say, a Süleymaniye in Istanbul or a Selimiye in Edirne. Probably because after all the design is rather simple: dome upon domes upon domes. But it looks nice.
