Help me, I'm being driven mad. I have a crystal clear memory of been in a UK seaside town. There was what looked like an old high wall but there was lots of entrances. Some went into pubs, one went into an open garden of a restaurant. Another into an old fashioned department store. Then an alley lead to the harbour. I'm sure its north England, around Morecambe way but it's possible it could be SW England. I know it's vague but I'm just hoping one Mumsnetter knows what the hell I'm talking about!
