Seal Sands / Greatham Creek Section Posts

A row of three identical World War 2 section posts can be found along the edge of the Seal Sands nature reserve.
The most northerly is open at both ends, although its view has been blocked by a later bank, internally some concrete shelves remain along the walls.

Due to land reclamation they are now inland, but would have overlooked a much larger Seal Sands during World War 2
