Casa do Penedo or House of Stone is located in the Fafe mountains of northern Portugal. Built by an engineer from 1972-1974, it utilizes 4 existing boulders to form the structure. Originally built as a vacation home, current owner Vitor Rodrigues is not quite sure what to do about the increasing number of tourists drawn in by his unusual abode!
Lacking electricity, the House of Stone does include a fireplace and pool, both made from stone. Most of the house is built from stone except for the roof, windows, and stairs.
Although it is not open to the public, if you happen to be in Portugal you are able to view the House of Stone from a distance.
