Sk for transmission
This is a bunker with many details and with, maybe, more questions. It looks as if it was built as a Sk. On the outside a modification gets our attention; it looks as if a moat along the central bunker was constructed in order to keep the groundwater out. Also on the inside we find modifications that were placed to control the water. Insciptions on the walls, if original, tells us more about the functions. You find this beauty along the Route de Saint-Omer from Calais.
Henk Adriaanse made the visit in the winter of 2009.
