The calades, what is this?

The calade is a technique for the gravelling of soils in which the material is the stone, the more often picked up locally. The stones are sunk vertically. It is said then that it is a standing ground to distinguish it from pavement which is a lying ground. Stoned paths were among the main accesses to the village. They allowed to mount all the necessary goods and on a daily basis, the most precious of all: the water.
