Does anyone remember where Old Chicago, the indoor amusement park, used to be?

I remember having a fun time at Old Chicago when I went as a kid. I was too young though to enjoy the Roller Coaster “The Chicago Loop”
Ah, yes. Some of my oldest memories are climbing on the Fun Factory there … not that I could remember that’s what it was called, until I read through the site RD pointed to. Also, I could have sworn it was more than two stories tall. Seemed to go up forever for a little tyke like I was back then. (sniff) 
SCHAZBOT—thought this one was gonna be right up my alley and be about RIVERVIEW! I’d already left Chi. by 1975. Oh well.
