Zuelke Building

A historic commercial building near Houdini Plaza in downtown Appleton, put up by Irving Zuelke, who also ran a music store inside the complex.

Irving Zuelke, who built the complex and ran a music store within it, is said to haunt the building. Staff and visitors near Houdini Plaza report hearing phantom music -- piano and violin -- drifting from upper floors of the building when no one is there. Doors open and close on their own, and lights flicker in the former music store spaces.
