The area is rich in history, having been used by the military since the napolionic era; not much now remain's of the barracks erected during this period, one being on the western side (coastguard cottages), whilst the other was sited between cliff end and foxhole farm, - this comprised of officers quarters, soldiers huts,and a pair of magazines. In 1816, once the threat of Napolion was removed, (after the battle of waterloo in 1815) they were auctioned off and removed. Today, there are 'humps' in the ground giving a brief 'footprint'.
The site was indeed a 'Starfish or QL' decoy site, between 1942 and 43, using lighting to mimic the local port of newhaven
The area really from cuckmere haven through to seaford is well worth walking, as there are various reminders of defensive positions, etc.
Good pic's.
( for an all too short while, I was park ranger, at the park living at Foxholes, so tended to take a lot of interest in said fortifications and history. )
