Odiham Castle (known locally as King John's Castle) is not actually in Odiham, although it isn't very far away, being nominally in North Wanborough. It isn't really in any village, though; it stands, peacefully, by itself next to the Basingstoke Canal, which - fittingly - does not actually go to Basingstoke.
I was fascinated by the poppies growing on the walls (above).
All sketches A6, executed in fountain pen. Top sketch also has Inktense pencil and then more fountain pen ink, both added after leaving the site.
