Stack Rock Fort is a 19th century Palmerston Fort built between 1850 and 1852, and upgraded in 1859. It is now a grade 2 listed building and is currently not used for any activities. It was first proposed by Thomas Cromwell in 1539 to protect the waterway, proposals were also made in 1748 and 1817 however it was not finally approved and started until 1850. The aim of it was to defend Pembroke Dock and The Royal Dockyard.
