Two-storey, type-22 hexagonal pillbox. Brick-shuttered, with embrasures at both levels and a strange vertical 'embrasure' that runs almost the whole height of the structure. Doorway below lower set of embrasures.
[Wills gives NGR - SS 916794: it is possible this is in fact a separate, but similar, structure].
