Places   (Help with places, streets and buildings in Wigan.)

Have i missed something on here with all the talk of the Nunnery where my uncle once lived Mr Dilworth no one has come up with what sort of Nuns lived there before it was divided in to two houses I know there was a small door embedded in the back garden and went into a pssage that led underground to a Alter where the Priest used to come and serve Mass there, for the Nuns, and also a portion of the wall in the Attics used to move if touched in one certain place and again thet led to steps and then underground to meet up with the Alter aforementioned
