Anti Glider Post
During the Second World War the Firth of Forth was of vital strategic importance to both the Royal Navy and the Merchant Navy with the naval dockyards at Rosyth, the docks at Leith and the deep-water anchorages available.  As this made the Forth a tempting target for the Luftwaffe many types of coastal defences were made including Anti Glider Traps.  These consisted of large concrete blocks or wooden poles set in cement to prevent gliders landing which would be then broken up on impact with these poles.  The posts often extended for several hundred metres at regularly spaced intervals and were no more than 1m high.  
Eastern Scotland has many lovely sandy beaches along its coastline so many were considered suitable for an invading army to land by gliders on the extensive sands at low tide. These defences were intended to slow down tanks and vehicles attempting to move inland and gaining a foothold in Scotland. While most of the posts have been removed there are still remains on some beaches including here at Ravensheugh beach and nearby there are Anti Tank Blocks including these less than a kilometre away..  Today thoughts of war seemed far away with the sight of a few people and their dogs enjoying the sands in warm sunshine.
