The caves were the first houses used by man, although they were used as a necessary refuge due to climate change. The caves were warm in winter and cool at the arrival of the summer's heat.

Man did not stop living in caves until its lifestyle improved considerably. Today, there are places that conserve whole neighbourhoods of this type of house, and a clear example of this is the Guadix region in Granada. 

Today, many of them have been refurbished and there are many examples of caves that have become original tourist establishments providing a different offer for spending a few days with nature.
