The story of this place
The heritage account for Cramond Island includes the Knoll defences and a barrier intended to stop shipping across the approach. Gun and searchlight positions helped cover that barrier.
The island’s military history includes First World War and later work. Its concrete remains therefore belong to a wider defensive arrangement built over time. The official account supports an anti-shipping role; we have not reduced that description to the narrower claim that it was only a submarine barrier.

What you can see
The relationship between the barrier, shoreline and positions helps explain what the remains were for. Reaching the island, however, depends on the tide, and does not confirm entry to the military buildings.
Check current safe-crossing information and weather, allowing enough time to return. The RNLI warns against wading back if cut off. In an emergency, call 999 and ask for the Coastguard. We do not provide a live crossing timetable or a guarantee that the route is safe.
