Derived from the former Cardiff Colour Map from Geographia , this revised map features colour-classified roads, places of interest, hospitals, car parks, railways and railway stations, one-way streets, pedestrian areas, administrative and postal boundaries. The map extends from Culverhouse Cross in the West to St Mellons in the East, and shows the M4 in the North with Penarth in the South. A comprehensive index of streets is included.
