Seend, Wiltshire: A Particular Part of a Brick Wall

The lower levels of this wall have been repointed and furthermore the brick is more recent and a bad match. I cropped most of it out because it was so unattractive. I need to revisit with a macro lens before any more "improvement" and "restoration" takes place. It is curious how older brick has been laid above newer. Reclaimed, presumably. Yet it could have been done so much better. A wall need not be strictly utilitarian.
