I'm currently looking for Universities in Switzerland that offers a BA in art history, but I can't seem to find any? There MUST be somewhere I can take my degree...preferably in the south of Geneva (the french or Italian part), but that doesn't matter in the first place.
If you don't mind a private university, Lugano has Franklin College. It offers the liberal arts curriculum of as much as possible. It's a pretty small school and costs far, far more than Swiss universities. As a student there I can tell you the experience is certainly pretty good, and you graduate in three or four years depending on the workload you're willing to shoulder.
Perhaps there are some continuing education programs that you can take at some of the institutions such as the Kunsthaus in either Zurich or Basel; you can also inquire at the Beyeler Foundation. Good luck!
Incidentally, I have a Bachelor of Arts Degree in Art History.
