You can go to virtually any college or university and study history. I concur with @ucbalumnus that you might want to browse the webpages and course catalogs of colleges that you are interested in to see the breadth of history courses they offer and in what areas - history is very broad. While I think you should remember that you are not specializing, it might be worthwhile to see - for instance - if a college has at least a few courses on African history or history of science or whatnot if you are interested in something special like that.
