From the second half of the 17th century, the Ascó snow well is the only one left in these areas. Located in the foundations of a house, it is constructed with crushed stone and has a pointed vault, with a circular floor plan and in the shape of an acorn. The upper beams rest on ridges at different heights for the snow conservation, which was poured out from a window. Its purpose was to fill it with snow or ice and have it available for the rest of the year. During that time the storage and distribution of ice became an important business that involved a significant part of the rural population.
