At first it looks like a bunch of boulders. Get closer and… what the!

How about this for bizarre?! Casa do Penedo (The House of Stone) was built in 1974 and is situated in the Fafe mountains of northern Portugal. Its unusual design looks like something out of the stone age! It has been built between four large boulders connected with cement mix. Despite it’s ancient look, the house does have normal features such as windows, a front door and a roof, although these have all been reinforced due to frequent break-ins. The door is made from steel and the windows have bars. Better to be safe than sorry though, right?! Rumor has it that this house was inspired by the Flintstones…
