I am saying that the early inhabitants chose to call the Church side of the lamp 'below' and the Stanhill side 'above'. I can see logic in this despite what the compass tells.
I am not suggesting that there was an early/original lamp at the Black Dog. I used that pub so that readers could picture what I was describing. I do think, without checking, that the Black Dog is at a higher point above sea level than the railway station and if so, folk would need to walk up to the Dog and down to the railway from the library.
