Located inside a gorgeous 16th century monastery, the city's 'architecture museum' is actually more of a decorative and applied arts museum, with much of the collections consisting of decorative details from the built environment that were lost during WWII. Permanent displays include beautiful examples of stained glass from the 12th century to the Art Nouveau era, a collection of tiled ceramic stoves, intricate door handles, and a selection of truly ghastly gargoyles. Keeps your eyes peeled for occasional temporary exhibits as well, which usually require an admission fee.
