Historic Background
A character area comprising a narrow coastal strip lying within the parish of Angle. Historically, this coastal strip has always been marginal land, outside the boundaries of cultivated land. In the past it has been used for rough grazing. However, it embraces many former occupation sites including several iron age promontory forts. Castles Bay Camp, opposite Sheep Island, is an unusual site that was possibly occupied during the early medieval period, and may feature post-Anglo-Norman Conquest military reuse. Lying at the mouth of the Milford Haven waterway, this area has long played an important defensive role. A gun tower was constructed in 1542 at East Blockhouse. A gun battery built on Thorn Island in 1859 was later converted to a fort, and finally to a hotel. In 1901-04 massive gun emplacements were built close the 16th century gun tower. This latter site was in use during World
War 2 during which a large camp was constructed as well as many smaller installations. The military still use the site, although the main function of the coastal strip is as a corridor for the Pembrokeshire Coast Path.

Description and essential historic landscape components
This historic landscape character area consists of approximately a 7 km strip of high, hard-rock sea cliff topped by a narrow band of moor, scrub and rough ground. The Pembrokeshire Coast Path runs along the entire length of this area. Although it comprises a very narrow strip of land, sometimes just a few metres wide, this area is very different from the highly cultivated land that bounds it, and for long sections there is no connection between the cultivated fields and the coastal strip. Essentially the historic landscape of the coastal strip is characterised by its many and varied archaeological sites. The most obvious of these are military sites dating from the 16th century through to the 20th century, including the earliest surviving military installation on the waterway, East Blockhouse, constructed in the 16th century, and now reduced to a tottering stone ruin on the cliff top. Also included is the grade II* listed 19th century fort on Thorn Island, built in 1859 and now converted to a hotel (itself grade II* listed), the coast gun battery at East Blockhouse constructed in 1901-04, and several dispersed installations such as searchlight batteries and gun emplacements. Buildings at East Blockhouse are still used by the military. Other archaeological sites include iron age forts, a possible dark age site at Sheep Island and numerous flintworking floors.

This distinct area is clearly separated from the enclosed farmland that bounds it inland.
