Las salineras artesanales de Salinas de Oro Curiosity · Salinas de Oro/Jaitz, Tierra Estella, Navarra Image of Salinas de Oro/Jaitz, not of the place itself. Documented since at least 1492, though probably of earlier origin, the Jaitz salt works exploit a salt spring — with a salt concentration far higher than seawater — which evaporates in small pools in the sun and air, following an artisanal method that has changed little since the Middle Ages. 1492 Photo: Patxi Txokarro (CC BY-SA 4.0) What to see and do in Salinas de Oro/Jaitz
