High Street (or the High Street, also High Road) is a metonym for the concept (and frequently the street name) of the primary business street of towns or cities, especially in the United Kingdom and Commonwealth of Nations. To distinguish it from "centres" of nearby places it is frequently preceded unofficially by the name of its settlement. In a town it implies the focal point for business, especially shops and street stalls (if any) in town and city centres. As a generic shorthand presupposed upon linear settlements it may be used to denote more precise concepts such as the urban retail sector, town centre sectors of employment, all small shops and services outlets and even wider concepts taking in social concepts. The smallest High Street in Britain is located in a small market town in Devon called Holsworthy. The street itself is no more than 100 yards long and there are only three shops located on Holsworthy's High Street.
High Street is the most common street name in the UK, which according to a 2009 statistical compilation has 5,410 High Streets, 3,811 Station Roads and 2,702 Main Streets.(Wikipedia)
