By Tim Binnall Apr 16, 2021 A 'UFO detector' that set off a bomb scare, a lightning strike that shattered a tree in seconds, and a mysterious 19th-century tunnel discovered under a home in Illinois were among the strange, unusual, and enlightening stories to pop up on our radar this past week. A farmer in Illinois found himself with a curious mystery on his hands this week when an attempt to repair a sloping sidewalk outside his home revealed a remarkably well-crafted and quite large tunnel that ran beneath his property. Comprised entirely of bricks, the intriguing passage measures approximately nine feet wide by nine feet tall and runs about 60 feet before hitting a huge pile of dirt that blocked wherever the tunnel is meant to lead. Believed to have been constructed around 1840, the purpose of the odd underpass is unknown as it could have been created to hold ice, served as a root cellar, or even been a part of the Underground Railroad.
