This is amazing! A two-story home with a four-story underground fortress is for sale in Blaine, WA. The owners are calling it the 8<sup>th</sup> wonder of the world. The fortress goes down 45 feet below the house and is over 1,600 square feet, not including many passages and secret rooms. The walls consist of three feet of concrete.
The owners say it was all hand dug and took over 20 years to create. The fortress is completely finished and stays at a constant 60 degrees year round. It would make an amazing bomb shelter, if nothing else. Or perhaps a place to put those teenagers with a garage band!
