Archaeology Notes

NR98SW 59 9264 8445

This concrete structure is situated at the top of the beach some 350m W of the Otter Ferry Inn. The building is probably the engine house to supply electrical power for the Boom Defence across Loch Fyne. The building measures about 4m by 4.6m with a large opening facing the beach. Leading into the water are at least seven small blocks which may have supported rails which held the landward (E) end of the anti-submarine boom. A pile of rails still survive alongside the structure.
