Reading Abbey has been closed to the public for several years now; I understand that there is a risk of faling masonry. It seemed pretty solid the last time I was there... at the time, I was playing with my new SLR (a second hand Pentax K1000) and took a series of black and white photographs in which, to be frank, the masonry and the autumn eaves were pretty much indistinguishable. So the photographs scarcely represent a solid ruin! Fortunately, I had another camera loaded with colour film, and those photographs helped me to interpret the monochrome ones.
This is line and wash, with sepia acrylic ink (and a cheeky splodge or two of white acrylic ink) applied with pen and dropper, on A4 HP Bockingford paper.
