The site comprises a building enclosing a hollow area containing the remains of two ovens with stone lined flues. A large amount of briquetage, fragments of coarse earthenware vessels made from the local Gabbroic clay made into plain rectangular slab-sided vessels, has been recovered from the site. These vessels were filled with sea water and heated by the ovens and flues to evaporate the water and recover the sea-salt.
