Peek inside Casa do Penedo, a house made of four huge boulders

Built in the early 1970s and currently nestled among a Portuguese wind farm, Casa do Penedo is a residence-turned museum. It would be cool to see how this was constructed!

Fun fact: despite being in the midst of a wind farm, the building has no electricity. How Flintstonian!

Bonus video: California's beloved Flintstones House sold last year for a little under $3 million.

The realtors created a lovely website about the home.
