We've been meaning to get over to this one for some time, so with a beautiful sunny day forecasted we decided to get the bikes out and looking at the map I gathered it was only a couple of miles away. 5 miles later of having my bones rattled on the uneven ground, we made it. Sadly it was locked up tight but the ride was worth it.
"6.7 m high x 6 m wide observation post built as a two-storey hexagonal tower surmounted by a concrete cupola. Constructed of 2 ft thick concrete, the lower level is a pillbox/strong point with a total of 17 machine gun apertures at two heights giving a 360 degree defence. The upper floor is reached by an open hatchway (no ladder). This is a 4.9 m wide room with a high pyramidal ceiling at the apex of which is the 1.8 m wide cupola containing a firing slot with steel flap in each of its six sides. The dominant feature of the upper room is a concrete platform above which is a 1.8 m wide by 4.9 m high look-out slot set in the South wall. From this position one can see above the sea wall, some 46 m distant, and across the mouth of the River Crouch."
