In the mountains of northern Portugal Fafe is a strange building, which has become an important tourist attraction. Casa do Penedo, translation stone house is a unique architectural style, very similar to the old shelters of primitive people.
Built just stone house seems carved into the rock, but in reality it is a modern building. Inside has all the necessary comforts: fireplace, pool, and the windows and the windows are armored, although no one knows why the former owners wanted this.
The house was built in 1972 and its construction lasted two years. Although not connected to the electricity grid, the interior is quite comfortable. Currently it operates a museum here.
