Hatfield is situated
on the main road and rail routes to the east coast of Scotland 20 miles
(32 kilometres) north of London.
Hatfield, as Hetfelle, was recorded in the Doomsday Book and the right to hold a market in the town was granted by Henry III in 1226.
The manor
was then owned by the Abbots (later the Bishops) of Ely, hence the later
name for the town of "Bishop's Hatfield" and the inclusion
of "Bishop's" in building names and locations around the town
to this day. The Bishops built a palace located near
the parish church of St Etheldreda's - the Great Hall of 1480(now known as the Old Palace)
still stands.
From 1538 after the dissolution of the monasteries under Henry VIII the town became known as King's Hatfield.
Princess Elizabeth
was resident at Hatfield House when the death of Queen Mary
in 1558 resulted in her accession to the throne as Elizabeth I. She held her first Council of Ministers in the
Great Hall.
Elizabeth I later appointed William Cecil, as her principal secretary. In 1607
James I exchanged the Cecil residence of Theobalds (near Enfield) for other properties including Hatfield House. Robert Cecil, the first
Earl of Salisbury started building the current Hatfield House at the
end of that year. His descendants occupy the house to this day.
Hatfield continued as an important town on the Great North Road until
the 20th century when Geoffrey de Havilland moved his aircraft manufacturing
business to Hatfield in 1933, developing a range of
civil aircraft. World War II forced a change
to military aircraft, which resulted in the Mosquito.
Hatfield's aviation heritage is recorded at the Mosquito Museum located
at London Colney 4 miles (6 kilometres) from Hatfield.

De
Havilland's, later British Aerospace, became
the town's largest employer of over 8,000 people. However the plant
closed in
1992. The development of the site into a major business park has progressed significantly
in recent years, with the arrival of major firms including T-Mobile,
Computacenter and Ocado.
The rapidly growing and highly respected University of Hertfordshire has
also centralised its activities in Hatfield and is now the town's major
employer.
