Merlin's solution was to import a stone circle called the Giant's Round from its home atop Mount Killaraus. Giants from Africa had originally brought the stones to Killaraus. They would pour water over the stones and use it to fill baths in which they cured their sick. Uther Pendragon went with 15,000 men to retrieve the stones but they proved too heavy to move. Laughing, Merlin transported them to Salisbury Plain using his magic and set them up just as they were. According to Geoffrey, they have stood there ever since as Stonehenge.
