The entrance to the Adana Müzesi. The name indicates, this is not "just" the building for an archaeological museum: when finished the complex will house all sorts of museums that so far were strewn all over town (or are newly created).

I have found that on the web one can find all sorts of references to the museums to be moved here, often as if they still are open and at their earlier location. This is true for articles in the Wikipedia (some language versions have been updated), and some maps, even ones that are sold commercially for navigation. In my mind it's wise to first head to the Adana Müzesi, rather than go on a wild goose chase.
