6Casa do Penedo (Portugal)
Casa do Penedo, or the “Stone House,” is a unique home nestled between four massive boulders in the mountains of northern Portugal. Built in 1974 as a vacation retreat, the house blends into its rocky surroundings, giving the impression of a natural structure rather than a man-made one. The isolation of the house, combined with its rugged, natural construction, makes it one of the most extraordinary and lonely homes in the world.
Why it’s special: The house’s integration into the landscape creates a seamless connection between nature and architecture.
