Squint Shot 031510

Yesterday's squint shot showed the right side of this unique building, but this shot shows a bit more of its interesting architecture. Bricks were formed to make a circle -- at one time maybe it was a small porthole to light the second floor? The sandstone blocks that are worked into a large arch look like they have worn down through the years -- was there something more definite etched at one time? Now the three windows inside the arch are boarded up -- but at one time did they have interesting glass? Oh, the questions -- any answers?
