A BIZARRE dwelling in northern Portugal’s Fafe Mountains has earned a reputation as a real-life “Flintstones’ house.”

    But its allure goes beyond its resemblance to stone houses from the classic animated TV series — it has bulletproof doors and windows, and a swimming pool.

    Nestled between four granite boulders, the extraordinary house, known as Casa do Penedo, or House of Stone, is perched on a mountain at an elevation of nearly 2,600 feet (792 meters).

    Once used as a holiday home by a family, it has become a growing tourist attraction after it was transformed into a local museum. Yet it’s not exactly clear why the original owners required bulletproof doors and windows.

    Portuguese photographer Ricardo Oliveira Mateus, 34, recently returned to the 16.5-foot (5-meter) tall house to capture its unusual character.

    He said, “It was built from four large boulders that serve as the foundation, walls and ceiling of the house.

    “Its construction began in 1972 and lasted about two years.

    “The house is fairly well equipped although there is no electricity it does have a fireplace and even a swimming pool which has been carved out of one of the large rocks.”

    Oliveira said the stone house is now a small museum of relics and photographs from Penedo’s history.(SD-Agencies)
