Coatbridge is a town which grew out of a series of 18th century hamlets on the road between Airdrie and Glasgow. During the 19th century these hamlets grew into the modern-day town of Coatbridge. A number of these hamlets constitute the neighbourhoods of Coatbridge. Overlaid on the older hamlets are modern-day council estates built as a part of programme of social housing construction in the 1930s and 1950s. There are approximately 27 distinct neighbourhoods associated with Coatbridge. A number of these neighbourhoods overlap geographically.(Further information: History of Coatbridge)
