The small town of Setenil de las Bodegas is home to around 3,000 people. The Andalucian town, northeast of Cadiz, Spain, was built along a narrow river gorge eroded by the Rio Trejo river. Many of the houses are built into & under the walls of the gorge itself, a tradition which has dated back to pre-historic times. They can live in the gnarled caves & just construct a façade. It’s perfect for blocking the hot & cold temperatures that sweep the country.
