Monument record LCS 127 - World War II anti-invasion defence barbed wire .

Two lengths of World War II barbed wire obstructions are visible as structures on aerial photographs located on the sea-front at Sizewell, Leiston, centred on circa TM47546319. The barbed wire is first visible on aerial photographs of 1940, but the defences are elaborated in 1941 with the addition of further entanglements. The first length of barbed wire runs as a continuation of a line of barbed wire to the north, recorded as LCS 125. It begins just to the south of the anti-tank cubes recorded as LCS 126, at circa TM47586334 and terminates at a second line of cubes roughly 340m to the south (LCS 128) at circa TM47586301. The second entanglement runs in an zigzag pattern to the west of the first, and again runs between the two lines of anti- tank cubes. However, this second entanglement extends to the south beyond the cubes and functionally becomes part of the densive complex recorded as LCS 115. (S1, S2). All barbed wire appears to have been removed by October 1945 (S3).
