The FUNCTION of an area is its reason or for being. In urban areas this relates to the purpose of a land use for residential areas, recreation, industry etc. The dominant function in different cities varies, for example, London is known for its function as a centre, whilst Newcastle is now attempting to be a city. Functions can change over time as well, in Newcastle the original function was as a region, which then changed to heavy industry and manufacturing with ship building and armaments at the forefront, and presently high tech industries and dominate.
The CBD
 The central part of cities is known as the Central Business District. This is often the site of the settlement where the city originally started and contains services, education facilities and businesses. It often has the buildings and is the most area of the city. The CBD of Newcastle can be found at the central Southern part of the city. It has the central motorway, the coast road, the national train line and the routes. It is the most accessible part of the city and for that reason the land values are highest and retailers such as HMV and major offices and businesses can be found here. The CBD is also on the original site of the settlement, selected because it was the furthest point downstream on the river Tyne that could be crossed and then (bridging point), it was also high up above the river against flooding but close enough to allow water access (wet point site). Other good original site factors are that the surrounding land would have been great for farming and locally available stone and wood was available for building, it was also high up so a good . The new CBD has the highest buildings to maximise the use of the land, the highest building density, some of the newest buildings due to (e.g. the Gate) and some of the oldest (e.g. the Theatre Royal), it also has entertainment and social functions such as the universities and the Civic centre.
