In Mechelen they have parking lots underground (but I don't think you mean this, do you?)
Brussels has got ancient castle-ruines underground: http://www.coudenberg.com/contentennew.h.
The train station in Brussels is also underground. Trams in Brussels drive both on and under the ground.
Hope this will help.
