When Craig Muir spotted an object while hiking the summit of a hill, he thought he was having a close encounter of the third kind. However, while not a UFO, the shiny, silver monolith in a muddy patch of Powys uplands was strikingly mysterious.
Following a spate of monoliths appearing around the world in 2020 – in the Isle of Wight, Romania and the Utah desert – conspiracy theorists speculated that aliens could be behind the structures. No one has yet come forward to claim responsibility for the Welsh monolith, which bears a resemblance to the one that features in Stanley Kubrick’s film 2001: A Space Odyssey.
