Cardiff North is one of the capital's four electoral constituencies. It is made up of the Council wards of Whitchurch/Tongwynlais, Gabalfa, Llandaff North, Heath, Rhiwbina, Llanishen & Thornhill, Pontprennau & Old St Mellons, and Lisvane and has an electorate of around 66,000.
Although the area is largely suburban and residential in nature the constituency benefits from a green belt to the north and areas of open space such as the Llanishen and Lisvane reservoirs as well as a number of areas of parkland. Many of the suburbs have retained their identity with thriving shopping areas and a wide selection pubs and restaurants. A centre of student population has developed in the Gabalfa area for students attending the city's numerous learning institutions.
Cardiff North is home to a number of recognisable Welsh land marks. The University Hospital of Wales is located in the Heath area and Velindre Cancer Trust is based in Whitchurch. S4C, the Welsh Language broadcaster, has its HQ in Llanishen as does the regions main Tax and Excise office. The Victorian fairy tale castle, Castle Coch, is located just outside the settlement of Tongwynlais north of the M4. The River Taff forms part of the Western boundary of the constituency and attracts many cyclists, runners and walkers who exercise along the Taff Trail.
Companies such as the directory enquiries service 118-118 and the pharmaceutical manufacturer GE Healthcare have sites within the constituency. The retail sector dominates with a number of supermarkets and retail parks plying their trade alongside small, independent outlets.
