WW2 searchlight building on the Forth. It is one of a row of three next to the remains of a six inch gun emplacement. at Charles Hill. Grey, eroded concrete now, they would have had camouflage paint in their day.

Searching for eider ducks and seals now rather than enemy ships.

The coast here is littered with relics like this – gun emplacements, pill boxes, tank traps, poles on sand flats to stop glider landings.  All gradually being reclaimed by nature.
