Hatfield is a town and civil parish in Hertfordshire, within the borough of Welwyn Hatfield, with a population of 41,265 at the 2021 census. The town has a long history — the settlement is of Saxon origin, and Hatfield House, home of the Marquess of Salisbury, forms the nucleus of the old town. From the 1930s, when de Havilland opened its aircraft factory, until British Aerospace closed it in the 1990s, aircraft design and manufacture employed more people in Hatfield than any other industry; today the town is best known as the home of the University of Hertfordshire and carries much of the modernist architecture of its post-war New Town era.
