Milton Keynes (/kiːnz/ KEENZ) is a city in Buckinghamshire, England, about 50 miles (80 km) north-west of London. At the 2021 Census, the population of its urban area was 264,349. The River Great Ouse forms the northern boundary of the urban area; a tributary, the River Ouzel, meanders through its linear parks and balancing lakes. Approximately 25% of the urban area is parkland or woodland and includes two Sites of Special Scientific Interest (SSSIs). The city is made up of many different districts.
In the 1960s, the government decided that a further generation of new towns in the south east of England was needed to relieve housing congestion in London. Milton Keynes was to be the biggest yet, with a population of 250,000 and area of 22,000 acres (9,000 ha). At designation, its area incorporated the existing towns of Bletchley, Fenny Stratford, Wolverton and Stony Stratford, along with another fifteen villages and farmland in between. These settlements had an extensive historical record since the Norman Conquest; detailed archaeological investigations before development revealed evidence of human occupation from the Neolithic period, including the Milton Keynes Hoard of Bronze Age gold jewellery. The government established Milton Keynes Development Corporation (MKDC) to design and deliver this new city. The Corporation decided on a softer, more human-scaled landscape than in the earlier English new towns but with an emphatically modernist architecture. Recognising how traditional towns and cities had become choked in traffic, they established a grid of distributor roads about 1 km (0.6 mi) between edges, leaving the spaces between to develop more organically. An extensive network of shared paths for leisure cyclists and pedestrians criss-crosses through and between them. Rejecting the residential tower block concept that had become unpopular, they set a height limit of three storeys outside Central Milton Keynes.
