The old lock-up

The winding streets in the old town do hide some secrets. I have lived here for nearly 25 years and never taken any notice of this historic door before. But as I came out of the lovely coffee shop Aroma I came face to face with The Old Lockup, attached to the side of the Guildhall, and taking my chances between buses squeezing around the very tight not-built-for-buses corner blipped it !
