The Janubio salt mines, in Lanzarote, are the largest in the Canary Islands and constitute a human landscape of great value, both architecturally and culturally. Nowadays, the “white gold”, which was so essential to the economy of the island until the recent past, is still produced. It is situated in a lagoon formed from the volcanic eruptions which produced a barrier of lava opposite the sea. It has been declared a Site of Special Scientific Interest.
