Original monument to the 99th Pennsylvania Infantry at Gettysburg
The original monument to the 99th Pennsylvania is now on Hancock Avenue. (Hancock Avenue Pt. 3 tour map) It was originally erected at the Devil’s Den and dedicated in 1886 by the regimental veterans association. When the state made funding available for Pennsylvania regimental monuments in 1889 it was decided to create a new monument on the Devil’s Den location, and the original monument was moved to the regiment’s secondary position on Hancock Avenue.
