2Casa do Penedo, Portugal

Nestled between four massive boulders in the Fafe Mountains of northern Portugal, Casa do Penedo (literally “House of the Rock”) is a stone house that looks as though it was plucked from a fairy tale. Built-in the 1970s as a vacation retreat, the house is constructed entirely from local stone and blends seamlessly into its rocky surroundings. While it has become a tourist attraction, the house’s remote location—accessible only by a dirt road—gives it an air of isolation and tranquility.
