Hornchurch is a suburban town in East London the London Borough of Havering. It is located east-northeast of Charing Cross. It comprises a number of shopping streets and a large residential area. It historically formed a large ancient parish in the county of Essex that became the manor and liberty of Havering. The economic history of Hornchurch is underpinned by a shift away from agriculture to other industries with the growing significance of nearby Romford as a market town and centre of administration. As part of the suburban growth of London in the 20th century, Hornchurch significantly expanded and increased in population, becoming an urban district in 1926 and has formed part of Greater London since 1965. It is the location of Queen's Theatre, Havering Sixth Form College and Havering College of Further and Higher Education.
Hornchurch is an Anglicised version of the Latin Monasterium Cornutum (Monastery of the Horns), a term that was also applied to the mother Abbey in Savoy. The earliest recorded use here was in 1222, meaning "church with horn-like gables" and it was recorded as "Hornechurch" in 1233. The horned bull's head mounted on the eastern end of St Andrew's Church, near the town centre dates from much later, around the 18th century.
In the Anglian Ice Age, 450,000 years ago, the ice sheet reached The Dell, just south of St Andrew's Church in Hornchurch, the furthest south any ice sheet reached in Britain. Hornchurch Cutting is a Site of Special Scientific Interest just north of St Andrews Park which exhibits the geology.
Stone Age tools, Bronze Age and Iron Age artefacts have been discovered in Hornchurch, indicating a lengthy occupation in pre-history. Roman remains, sufficient to indicate a settlement have also been found in South Hornchurch. Hornchurch originates from around the 12th century when Henry II gave to the hospice of St Nicholas and St Bernard, Mountjoux, in Savoy as a gift. A prosperous Hornchurch Priory was established, near the parish church, but the monks were forced out during the 14th century when a new law banned foreign land ownership.
