World War One Audit of Surviving Remains (3 July 2013)

Maps in a War Office file (The National Archives WO 78/5182) show an anti-submarine boom between Cloch Point (where mooring blocks for the boom survive) and Dunoon in both First and Second World Wars. The maps suggest that the Dunoon end of the boom was attached on the shore below Castle Hill. In the First World War the ‘gate’ into the upper Clyde was nearer the Dunoon bank.

Information from HS/RCAHMS World War One Audit Project (GJB) 3 July 2013.

A First and Second World War anti-submarine boom is known to have been constructed between a point at or near to Cloch Point across the Firth of Clyde to Dunoon (NS 176 763). The location of the boom ends is uncertain.
