Les Tosques cave
Les Tosques, El Bon Pastor or Sant Martí cave has a cumulative depth of 22 metres and a length of 120 metres. The cave has been formed within tufas, which are porous materials that allow the formation of cavities in their interior. Since tufas are rocks that are easy to cut, the cave has undergone various artificial alterations (stairs, galleries, rooms, etc.). Calcite precipitation does not stop and the growth of tuffaceous masses continues to this day. In certain areas of the cave, calcite growth can be observed on rock surfaces carved by man. The existence of scribbles made in the early 20th century, now covered by calcite that is still translucent, informs us that it has taken a century for this layer of material to form. Unfortunately, the alterations that the cave has undergone have caused it to lose its archaeological potential.
