Looking a bit closer, the boundary that "almost" aligns with these walls
is an admin_level=10 boundary, which is not based on OS Open Data. I
have no idea where it came from. This admin level is used in Scotland
for Community Councils, and there is indeed one called Northmavine in
this location. The boundary across the isthmus appears to be a straight
line, without the wiggle we can see in OSM. I will see if I can import
the official boundary soon.
Bottom line: probably best to leave the walls alone as it looks like
they are not intended to align with the community council boundary.
