Maine is no stranger to old mills. All across the Pine Tree State, you'll find mills that were once used for a variety of different industries. Some lay barren, sinking into the earth as they rot away. But others are given a second chance at beauty. That includes the 1774 Grist Mill in Lebanon, Maine, once a thriving mill that saw production and need decline. But someone had a vision to restore the old structure and the results are an eye-popping luxury oasis.
