Magic Roundabout (Hemel Hempstead)
The Plough Roundabout (known locally as the "Magic Roundabout") is a ring junction in Hemel Hempstead, England, notable for its design comprising six mini roundabouts connected in a circle by two-way roads. The local name stems from the children's television programme The Magic Roundabout, similar to the Swindon Magic Roundabout.
