Mystery Arch

I had a roll of film from this Spring's flooding that i just got around to processing. To be honest I forgot all about it. 36 exposures and 30 keepers. I will share a few with you.

This bricked in archway mystified me. It is just there as if the ground covering the lower opening was not there at one time. Perhaps they filled in an entrance to a lower level 100 years ago? The building is far to decayed and dangerous to enter so I may never know.
