Please also see ‘Military Boundary Stones in SE Cornwall’ to focus on military boundary stones located across the River Tamar in S.E. Cornwall. These stones are included in the Plotting Plymouth’s Past database because they are primarily associated with the needs of the Admiralty, the Royal Naval Dockyard and the defence of Plymouth.
