Spain´s "Alleys of Stone"

"Forming a labyrinthian stone maze are the natural karst formations of the Los Callejones de Las Majadas or the "Alleys of Stone." 

 Besides the maze like set of "alleys" the stones also resemble bridges, arches, walkways, stone people, doors, plazas, and monoliths all named accordingly: the Dog, the Whale, and many more. 

The unusual rock formations were sculpted by slow differential erosion by wind and water over millions of years. The twisting passageways are easy to get lost in, and so two main walkways are marked through the "alleys."

Cattle herders in the area have used the stone walls as natural cattle enclosures for hundreds of years, and in some places you can still see remaining pens." Photos by jfpozo Source: www.panoramio.com
