Remains of coastal army camp with shooting butts, etc.
T.Driver, RCAHMW, 18 April 2005.

A military camp and rifle range occupied the site in the first half of the 20th century, and a Prisoner of War camp was constructed on the site in 1919, for German prisoners still in the UK after the cessation of hostilities. 
The holiday park developed from the 1970s resulting in heavy landscaping since the end of the military use of the site, and no relict remains, apart from a surviving plaque and a possible shed, can be seen of the former military camps within the park boundary.
