Mysterious 10-foot-tall monolith that "looks like some sort of a UFO" pops up on Welsh hill

As mystery surrounds Catherine, the Princess of Wales, it also abounds in the country named in her royal title. A massive steel monolith nearly the height of a semi truck has popped up in Wales, according to local reports – and nobody knows where it came from. 

WalesOnline reported on Tuesday that locals have come across the 10-foot-tall object on a hill in Hay-on-Wye, an area known worldwide for its books and bookshops. One local resident, Richard Haynes, told the outlet that he came across while out running on Hay Bluff, which he does regularly. 

"I thought it looked a bit bizarre and might be a scientific media research thing collecting rainwater," he told WalesOnline. "But then I realized it was way too tall and strange for that."
