Full Description

1993: Cudmore Grove Country Park was, during World War Two, a coastal artillery site housing 4.7" guns.<1> There were two emplacements, which are shown on maps dated 1960 and photographs taken in 1974.<2><3> Now they lie as broken concrete on the beach. Two photos of site.<4>

During World War Two, what is now Cudmore Grove Country Park was a coastal artillery battery with two 4.7-inch guns, probably of World War One vintage. A Battery Observation Post was the central command position, horizontally-aimed searchlights swept the sea at night from concrete bunkers, and pillboxes guarded the perimeter against ground attack.

In 2007, two pillboxes still survive, both in good condition. The two gun casemates now lie as broken concrete on the sands but remain very recognisable from the large ring of gun-holding bolts, the holdfast. Similarly, the Battery Observation Post is now shattered concrete on the beach, as is one of the two searchlight emplacements, both recognisable from the distinctive shapes. The remaining searchlight emplacement survives as a concrete base on the cliff edge.

After 60 years, very few WWII 4.7-inch coastal artillery sites still survive in anything approaching significant form. All the remains at Cudmore Grove, including the extant pillboxes, the broken emplacements on the beach and the remaining searchlight base, are important features of WWII archaeology, part of the history and heritage of wartime Essex. The loss of any part would be a loss to the integrity of the whole.
