Stonehenge is a famous location on Earth.
During the events of Ben 10: Destroy All Aliens, Tetrax's ship was shot down by Retaliator. Ben was knocked out of the ship, so he transformed into Diamondhead to survive. Diamondhead couldn't figure out where he was, so he started walking, hoping to find a way back. Due to Tetrax enabling one of the Omnitrix's functions so Ben wouldn't revert to normal, Diamondhead was transformed into Four Arms. He was then attacked by Retaliator. Stonehenge was destroyed during their battle.
- According to Retaliator, Stonehenge is a Galvan practical joke.
