A builder from a Welsh town has said he was “taken aback” when he spotted what he assumed was “some sort of a UFO” at the summit of a hill.

Craig Muir, who is in his 30s, came across the alien structure, which actually turned out to be a shiny, silver monolith – a large single upright block of stone – during his regular hike up Hay Bluff, in Powys, Wales, in the morning.
