The little fountain

Down the street, lies a fountain directly carved in the rock. The stone wall located above the basin closes the entrance of an horizontal tunnel, a water pit, which was dug several metres. This drains the seepage water until the pipe. The excavated rock is a limestone, relatively hard, made up of many fragments of organisms (shells, corals ...). This rock, called molasse, allows the seepage water to flow: it is permeable (spongelike).
