Newport Tower, Newport, RI

Speculation has swirled around this stone structure in Newport’s Touro Park for centuries. Was it an observatory? A windmill? Nobody knows for sure. Twenty-eight-feet tall and estimated to be 500 years old, it’s curiously located and perfectly aligned with other points on the planet, including 5,000-year-old Stonehenge. Some archaeologists even consider the tower to be evidence of pre-Colombian contact in the Americas.
