Salt House, Port Eynon has been described as a Uncertain although is doubtful that it was such.

There are masonry footings remains.

This site is a scheduled monument protected by law.


Situated on Port Eynon Point overlooking the bay are the ruins of a building known as 'The Salt House'. It is a scheduled ancient monument and has been extensively excavated by GGAT. The site consists of a set of stone built structures, some now hidden beneath the sands. The beach structures consist of 3 stone lined chambers with walls over lm thick, the largest chamber being 20m by 3m. At a higher level are a group of 2 storey buildings with thick fortified walls. This site has attracted some interesting stories about its history. The so-called historical annotation of the Lucas family claimed the building was erected in the mid 16th century, and fortified by John Lucas, who also apparently also fortified Culver Hole, connecting the two via an underground passage. From this stronghold, aided by a group of lawless men, he engaged in piracy, resisting all attempt by the authorities to dislodge him. The history claims that 7 generations later another John Lucas found a rich vein of paint mineral and exported if from his base at the Salt House but shortly after his death the building was ruined in a storm. The name of the building was said to come the fact that the sea washed against the battlements. Although interesting this history was later shown to be a fabricated family history written by the Rev. Dr. J.H. Spry during the 1830s in connection with a family lawsuit over the ownership of property. The steady erosion of the site by the sea prompted excavation of the site, undertaken by GGAT in 1986-8 and again from 1990-3, which revealed the true history of the site. It appears to have been originally built in the mid 16th century as a site of salt production. The main building still visible today was used for occupation and storage whilst three large chambers on the beach were used for the salt production. The site was chosen for the high salinity of the bay with little fresh water contamination. The sea water would enter the beach chambers at high tide where it would be stored in a reservoir. The water would be pumped into large iron pans and slowly heated and evaporated. As the salt formed it would be scooped off and stored in the northern part of the main building to dry. The first knowledge of a salt house at Port Eynon comes from a letter written in the 16th century about a ship carrying salt out of Port Eynon. A 'saullt house' in Port Eynon is also mentioned in a document of 1598. It would seem Welsh salt houses of the later 16th century were amongst the most advanced of their day. The value of the salt is perhaps shown by the fact the site was enlarged and fortified during the 17th century, with the inclusion of musket loops within the thick walls. It appears salt production ceased around the mid 17th century. Some of the structures were subsequently demolished but occupation continued in the main house. The most recent being the use of the northern end as oystermen's cottages, which were finally abandoned c1880. (Glamorgan-Gwent Archaeological Trust HER–ref. Poucher)

No suggestion the site was fortified before 1600.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown.
Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
