These gates at the south end of Mills Place open onto a parking lot across from the Burke-Williams Spa. (That's B-W's shadow in the foreground.) You can easily walk around them to the parking lot. I wonder what they used to open onto? They're not the gates to the alley, but some gates. Others just like them mark the entrance to a bar/restaurant further north. I don't know how old they are but they look pretty old. The building peeking from beyond is the quirky Castle Green. I've given you only one picture of it. Must do more.
One last shot of Mills Place tomorrow, then onward.
