The salt-pans can be found 3 km away from Rio Maior, in a valley at the bottom of Candeeiros Mountain. Surrounded by trees, vineyards and other cultivated lands, they are considered a natural wonder, once the sea is about 30 km away. The ensemble presents itself like a tiny village of cobblestone streets and wooden houses next to wich stand out some curious tanks of irregular sizes and shapes.. In spring these tanks are full with salt water giving origin to white pyramids of salt. History The oldest document referring to the Salinas dates back to 1177, but it is believed that salt was already explored in Pre-historic times. Candeeiros is a limestone mountain region with many fissures in the rock, which enables the rain water to penetrate forming undercurrents. One of these undercurrents passes across a very extensive and deep rock-salt deposit and feeds the well in the centre of the pans. This water is seven times saltier then the sea water. The rock-salt deposit which occupies the region of the Portuguese Estremadura, between Leiria and Torres Vedras (about 100 km long),was formed millions of years ago after the retreat of the sea that once occupied the region.
