#8: Rhode Island’s Viking Tower
Rhode Island’s Viking Tower remains an enigma, captivating tourists with its mysterious origins. Nestled in Newport, this structure’s builder and purpose are unknown, leaving much to the imagination but little in the way of verifiable history.

The tower could have been a historical marvel, purportedly constructed by Vikings, making it one of America’s oldest structures. Alternatively, it might be the whim of a wealthy eccentric. Either way, without concrete evidence, its allure remains speculative.
