South Hook Fort

South Hook Fort stands on the northern shore of Milford Haven in Pembrokeshire. It is a Grade II* listed building built as part of the inner line of defence for the harbour. The fort is located in Herbrandston parish, at South Hook Point, about 200 metres north of the cliffs. Its D-shaped structure has four walls each four feet thick. Inside, a horseshoe-shaped two-storey barracks block occupies the centre. The fort originally held twenty guns facing the sea, later adjusted to improve defence. The fort is worth visiting for its role in the Palmerston fortifications meant to protect Milford Haven. Work began in 1859, a year before the Royal Commission published its defence plans. It formed part of the double defences of the harbour, designed like nearby Hubberston Fort. During the First World War it was fully manned, and in the Second World War it was used by WRENS to control naval movements. The fort was later sold, requisitioned, and decommissioned before becoming part of the South Hook LNG terminal jetty. Visitors find a solid brick fort surrounded by a deep ditch and a bridge for access. The barracks block and covered walkways show how the fort was organised for defence. Earthworks protect two separate batteries that once held the guns. The site is also important for wildlife, serving as a roosting and hibernation place for protected horseshoe bats. The cliffs nearby and views across Milford Haven add to the setting. The fort’s history is visible in its thick walls and military layout.
