Natural Monument - Cárcavas de Marchal

Cárcavas de Marchal is consisting of a solid clay with beautiful badland forms. The origin is in a movement of Earth's plates that caused the sinking of the area, giving rise to a rift valley. This depression, over time, was filled with soft materials, mainly clays and silts. Thousands of years later, due to the low vegetation, frequent torrential rains  and the drag of materials was creating this landscape of ravines. These formations are since history used for creating cave houses where the villagers are still living in. Although there are fewer homes built in the formations, there are still many preserved that can be seen along the route that starts at the village entrance, marked with the sign 'Natural Monument'.
