It consisted of congregated metal buildings painted in a circus theme and at one time held live circus shows. Started in early 50's it lasted a decade before it closed
and rotted to point the land owner tore what was left of it down around 2011. when they rebuilt the US422 and Pa 38 Interchange
I remember as a kid riding pass the brightly painted yet fading metal buildings and always wondered about the abandoned place and at one point the Pittsburgh Press ran an article all about it and how it was going to partly disappear with the realignment of an intersection.
Seems a family got the idea to run the place as a road side attraction and in fact they had real circus type animal acts people could see but with ever increasing costs to keep the place running and ever increasing rules on maintaining the animals and fact insurance carriers no longer wanted to write policy's for such places they slowly all started falling away and closing. Now there where plenty of rumors a wild animal got loose and killed or maimed some one but this was never the case with Circus town a panther did get loose one time and was quickly recaptured .
How ever a lion did get loose at Luna park in Pittsburgh Oakland section which was one of the things condemning that park.
There is very little you can find in the way of pictures or history on Circus town as is the same case with Old McDonalds farm which was a large petting Zoo along US 422 outside of Butler as well it was still running into early 70's near Big Butler Farm Show grounds when it abruptly closed and is now a concrete forms plant.
It had a large barn and many fenced in areas with all kind of animals you could pet.
But again details on the place and pictures are very hard to find.
These are just 2 of many road side attractions now lost to memory and now mentioned in old tales and rumors of what once was.
While many road side attractions had a very seedy notorious side these 2 did not appear to be so.
