This is the bizarre UFO spotted hovering over a medieval fortress in North Wales.
The amazing footage shows the disc-shaped object drifting above the fort for at least 40 seconds before disappearing behind one of the turrets.
It was captured on camera in broad daylight last September by Owain Powell and uploaded to the “UFO Alien Sightings” channel on Youtube.
The clip, which appears to have been filmed from the Maes in Caernarfon, shows a small dark object floating over the town’s iconic castle.
Then as the camera zooms in, the object begins to descend slowly before disappearing out of view behind the castle walls.
