The Magic Roundabout in Swindon, England, is a ring junction constructed in 1972 consisting of five mini-roundabouts arranged in a circle. Located near the County Ground, home of Swindon Town F.C., its name comes from the popular children's television series The Magic Roundabout. In 2009, it was voted the fourth-scariest junction in Britain.
