In this picture you can see the second doorway on the north side. Behind this wall a pitched roof leads to the clerestory which to my regret I haven't got a good picture except for a slight peek in the one below. (This picture shows the clerestory from the other side). The clerestory is supported by internal pillars as I showed way back in this post.
...and I've just realised that this was rebuilt some twenty years after the Black Death killed a third to half the population of England, no taking silly test tests to see if you had the lurgy back then, no godforesaken masks either just: Attishu, attishu, we all fall down. No doubt twenty years from now they'll still be waiting for their precious vaccine while face masks will have become implanted hermetically at birth along with health passports courtesy of the Gates Foundation...
