At 822 feet, Arthur’s Seat is the highest elevation in Edinburgh. It was formed by an ancient and now dormant volcano. The cliff is named after King Arthur, the legendary British hero who fought the Saxons until his death in battle in the early 6th century. This is also the site where King David I of Scotland fell from his horse during the 12th century. He was about to be killed by a stag when he envisioned a cross between the animal’s antlers. In gratitude for being spared, he founded the nearby Holyrood Abbey in 1128.
