Stack Rock Fort

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.

In 1850, with the rise of Napoleon III in France, and with the new French king's occasionally bellicose threats towards Britain, the time had finally come to put the plans to build a fort into action.

However, after the foundations had been started in 1861, the design for the expansion was amended to have stronger granite piers supporting iron gun shields.

[5] Eventually the concerns about Napoleon III's intentions proved to be unwarranted, and the fort never saw actual combat.

[8] Concerns over the security of a nearby LNG jetty were raised in 2013, following the discovery of potential trespasser activity.

Land Registry records show[10] that it was sold in January 2021 for £191,000 to community interest company (CIC) Anoniiem.

A small number of men manned the fort during World War I and by this time, only two 12-pounder QF guns remained.
