This Pillbox is one of a pair defending the Blackwell Bridge crossing of the River Skerne in Darlington
The structure is now deeply buried in the undergrowth and tricky to approach
The pillbox itself is not like any other i’ve ever seen, it seems to have been constructed from pre-fabricated sections
Several areas have ripples that look like they were cast against corrugated iron sheets

Ugh – to think we were facing invasion. Thank you for the wonderful research.
Corrugated sheeting was often used as shuttering when pouring the concrete.
