Roundabout constructed in 1972 in Swindon, Wiltshire, United Kingdom, designed by Frank Blackmore, inventor of the mini-roundabout. The roundabout joins five roads and consists of a two-way road around the central island, with five mini-roundabouts meeting the incoming roads. The name derives from the popular children's television series, "The Magic Roundabout", and is considered "magic" because traffic flows in both clockwise and anticlockwise directions. This is achieved by surrounding the main island with one smaller roundabout per entry/exit street. This pattern directs traffic in the usual clockwise (in LHT installations) or counter-clockwise (in RHD installations) manner around each mini-roundabout. Exiting the
Roundabout intersections are called "rotaries" and the state enforces that restriction. The term "traffic circle" is not used in the United Kingdom, where most circular junctions meet the technical criteria for "modern roundabouts". However, in some parts of the English Midlands, such as in Birmingham, roundabouts are commonly called "islands", which conflicts with the more generic use of the term "island" as a structure to divide traffic flow, and can cause confusion. In the Channel Islands a third type of roundabout, known as "Filter in Turn", exists. Here approaching drivers neither yield to traffic on the roundabout, as normal, nor have
