Although I thought I remembered from my visit at Gettysburg that the Lutheran church there had no belfry, just a cupola. Hmmm... maybe it was different back then ... here comes a photo of Christ Lutheran Street in Gettysburg, 30 Chambersburg St. :
Edit - You are correct, Christ Lutheran Church was the hiding place of Elizabeth Butler.
It is almost impossible to see from ground level, but there is a bell hanging in that cupola. You can see it in the illustration in post # 3.
According to my source - Elizabeth Butler was able to run and hide in the (Christ) Lutheran Church on Chambersburg Street in Gettysburg.

Christ Lutheran Church, Gettysburg, (which you really must visit on a summer Saturday evening for its free program "Songs and Stories of a Civil War Hospital.")
*"She was marched with the rest down the street and there was such a crowd that when they were opposite the Lutheran Church, in the confusion she slipped into church without being seen, and climbed up into the belfry; she stayed there for the two days without anything to eat or drink." http://www.gdg.org/gettysburg magazine/gburgafrican.html
