Very cool! This would be a fun way to design a ride. Find an old picture then go and find that place (if it still exists). And create a topic thread for it! Might have to try that!
Looking up the history of that church, I thought this would be neat to see:
Soldiers used the interior walls to draw scenes of battle, write messages, and leave names of troops, companies, and soldiers. The walls were whitewashed after the war to cover the graffiti. In 1938, during renovation work, the writing on the walls was exposed. Portions of the graffiti are now visible behind plexiglass frames".
