History
On a raised beach between Pedn-myin (penn, head and meyn stone) and Lowland Point are the 2nd-century, Romano-British Trebarveth saltworks (grid reference SW79651933). Gabbro is the predominant rock here and weathers to a rough clay. Sea water was boiled in two rectangular, stone ovens within an oval building, The residue salt was packed into pots made from the gabbro clay, and course, red pottery sherds (briquetage) can be found in the nearby cliff. Some of the sherds still have potters' fingermarks on them. The ovens measure 150 cm by 40 cm and if packed with vessels 15 cm high, the oven would hold 50 lt of sea water. With the water containing 3% salt by weight, each operation would produce 1½ kg of salt. The saltworks are within a field system and some of the remaining walls stand up to 1 m high.[4][5][6]
