My previous ID of this building was incorrect. I was actually there, today and realized my mistake. The red barn and house in your picture was the Peter Fry farm.
my Brother and I visited Gettysburg back 2014, one thing I failed to do was be consistent in labeling my pics, especially the buildings, so hopeful on this fine forum those of you can help ID for me.....
Also, quite recent is the addition of 3D imagery for the town and most of the battlefield. You can tilt the view by holding the Control key while dragging with the left mouse button. Unfortunately, the 3D imagery stops short of the round tops.
