Red Hills are formed as a result of generations of salt making, deriving their colour from the rubble of clay structures used in the salt-making process that have been scorched red by fires used to evaporate sea water to make salt cakes. They date from the Bronze Age, Iron Age and into the Roman period."@en . . . . . . . . . "10982084"^^ . . . . . "15557"^^ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
