The caves of the primitive Carpetanian settlement of Caraca are a window in time, from the first Carpetanian inhabitants to the present day, representing the different cultures that have populated the Tajuña valley over time. The current state shows the deterioration typical of a hillside made of marl and gypsum that is brittle and easily eroded. In the time of the Carpetanians, it was a troglodyte settlement with interior passages that connected different galleries, had water channels, warehouses and houses protected from intruders at a certain height from the ground, accessed by ladders and ropes. In the middle of the last century, the Risco de las Cuevas was the setting for several films.
