Underground Ancillary Buildings, Culver Battery, Isle of Wight

Many thanks to Urban Mole for alerting me to this one. Urban Mole is famed throughout the outer Freshwater area for being the first person to climb the supposedly 'unclimbable' south face of the second Needles rock unaided in 2016. Due to embarrassing information I have on her, I was able to extort the location of this place, using blackmail and a little bit of tickling to boot.
This structure is a semi-sunk service building, part of the military coastal battery on Culver Down and used in connection with the direction finding cell positioned close to the cliff edge.
