Dave Chappelle spent nearly $13 million to save and rebuild a landmark in his hometown of Yellow Springs, Ohio. He bought the 1872 Union Schoolhouse - the first integrated school in the village - and turned it into a 19,000 sq ft home for public radio station WYSO. The station moved in and never looked back. "If you have the opportunity like I did, to invest in your community," he said, "then it's one of the greatest investments I've ever made."

Cape Hatteras Lighthouse is the tallest brick lighthouse in America, nearly 200 feet tall. At its closest, the Atlantic had come within 120 feet of its base. So engineers lifted the entire tower onto steel rails. They rolled it more than half a mile inland, five feet at a time. It took 23 days. Not one new crack formed in the century-old brick.
