Archways on the ends of buildings that have been bricked up, so now they are just walls. Then they've been painted over white, and I've been walking past them for a year now, and never noticed them. There's two in the end wall of a newsagents near to where I work, I've been inside the building before, it's all higgledy-piggledy three steps down, five up and you end up on the same level you were before, you walk down a corridor and only turn left once, but somehow end up where you were when you started - inside, it's that sort of place, so clearly nothing like the original warehouse or whatever it might have been to have these openings in the end wall. Weirdly the bottom of what would have been the opening is about five feet up in the air, so it's got to be some sort of loading bay, and arch at the top is about six feet above my head. I was walking to my bus this evening, having worked late on a Friday afternoon, a Friday afternoon, and morning for that matter,when I was meant to be on holiday. So, traipsing along as I was, at the end of my work day, when I had been looking forward earlier in the week to a day when I could get out and see something really interesting I hadn't seen before today, when I chanced to look up, and I noticed the tiniest shadow in the brick work and found myself looking up at a bricked up archway that I'd never seen before today! So a good end to not so hot a work day!
