This is the original brick outfield wall that made up center and left center fields of Forbes field. It is preserved with the original dimensions and ivy along with the flag pole.
The Pirates left Forbes Field in 1970 to move to the disgraceful Three Rivers Stadium, and the park was torn down a year later. All except for this wall of course.
It was over this wall that Bill Mazeroski hit his World Series winning home run. Every year on October 13, people gather at the site and listen to the radio broadcast of the home run.
A great, well preserved piece of baseball history. It's located in the Oakland neighborhood on the grounds of the University of Pittsburgh. Posvar hall now stands on the location of home plate.
