Lera
At Lera, salt is produced in accordance with the mediaeval tradition; the production procedure was only slightly modernised by the Austrians in 1904.
Salt is being made in the petola, a layer of biosediment that prevents sea mud turning into salt and undesired ions building up in salt crystals. The petola is a special feature in the salt-making procedure, as it has been preserved only at the Sečovlje and Strunjan Salina. The Lera salt-pans are not only an exceptional technical heritage, but at the same time co-create this unique cultural landscape at the junction of land and sea. The different life environments of the Sečovlje Salina are closely-knit in the interchanging worlds of sea, brackish water, fresh water and land. At Lera, the habitats of plant and animal species are limited to diversely saline salt-fields, channels and levees.
