Castle Rock, on which Edinburgh Castle is built, is the eroded remnant of the basalt plug of an unnamed, extinct volcano. Arthur's Seat, about a mile away, is the main peak of a group of volcanic hills of the same age and composition as Castle Rock. Features on Arthur's Seat suggest that there were multiple volcanic vents in the area 350 million years ago. Subsequent glacial erosion has left the isolated features seen today.
