Granada, Spain is known as Europe’s “capital of caves”.

The Sacromonte and Guadix caves in Granada are home to communities that still enjoy the ancient Spanish cave-dwelling way of life, which dates back to the 15th century. Nestled in a rocky formation here are 2,000 underground houses, discreetly carved into the stone. In the past, these caves were where people fled to escape religious and racial persecution. Today they offer a place where residents continue to live off the land how people used to centuries before them.
