Thank you Rosie99, I'm quite new to this game and hadn't thought to look at what came before and after ... certainly a good idea.
Thank you too Stan, I hadn't found that map web site (but will now be adding it to my favourites) and there actually appears to be two Methodist Chapels marked quite close together, long since gone but I think where they were is now called Thomas Street and it is quite a steep bank so a good contender.
Thank you both again for your help,
Carol
