These sites have been on DP before, however, I found myself in Somerset over the weekend and decided to have a quick visit. The sites are located in the Mendip Hills.
Brief history - these sites were built during the war to act as decoys to lure the Luftwaffe away from major cities and military installations. The sites posted here were designed to decoy bombers away from Bristol. The decoys were known collectively as Starfish and used water and creosote to simulate incendiary bombs exploding. In addition glow boxes were also installed at the site to simulate street lighting and railways etc. These glow boxes were powered by electricity generated by generator sets housed within the control buildings shown in this post. The idea was that the Luftwaffe would bomb the simulated fires and lighting as opposed to the real thing. Whether it worked here or not is open to debate.

Entrance protected by blast wall
View from roof looking down at blast wall
Bases for Coventry Climax petrol generator sets
Air inlet for petrol engines or cable ducts ?
Being where this place is located high in the Mendips this stove base would have been well
and truly needed
Concrete reinforcement showing through in the roof slab
The doorways between the generator room and control room
These pipes were probably used to provide cooloing water to the petrol engines
