Tophane means "canon foundry", the district is named after this building. The foundry was established by Fatih Mehmet, and enlarged under Beyazit II. Even the one that followed it, from Süleyman the Great's time, has disappeared, this one is from Selim III, 1803. It has finally become an exhibition hall. A good one. Nice views from the platform in front.

There was an exhibition with works from German artists.
