Where is the historic building of Stack Rock Fort located?

Stack Rock Fort sits on a rocky island about 800 yards off the western coast of Wales near Milford Haven. Built between 1850 and 1852 and later upgraded, it has been under private ownership but effectively abandoned for almost a century.

A fortification at Stack Rock was first proposed by Thomas Cromwell in 1539 to protect the waterway, although this would not actually come to fruition at the time. Similar proposals were made in 1748 when Lewis Morris carried out a survey of Milford Haven, reporting on shipwrecks and navigation and recommending that a small fort be built here.

The Royal Dockyard at Pembroke Dock, located along the Milford Haven Waterway, was deemed in need of further defenses against attack from the sea, especially in light of a possible invasion of Britain from France under Napoleon III. Due to its strategic location near the mouth of the waterway, Stack Island was once again in the spotlight, and construction of a fort was completed in 1852.
