Behold the amazing whimsical Wing’s Castle! Wing began constructing his castle more than 45 years ago, and is still working on it. He never received any kind of architectural schooling. The castle’s interior is 3400 square feet, and some of the towers reach up four stories. It is constructed of more than 500,000 stones. He also made his own stone circle. But the really impressive thing about Wing’s Castle is the fact that it is constructed from more than 85% recycled materials!
