Hertfordshire

County in England

Coordinates:	51.84, -0.27
OS grid ref:	TL 19 17

Hertfordshire sits immediately north of London, where the outer edges of the metropolis give way to rolling countryside: parts of the Chiltern Hills and the fertile valleys of the River Lea and its tributaries shape a patchwork of arable fields, parkland and commuter suburbs. A strong Green Belt preserves many villages and woodlands, so the county often feels like a comfortable transition between city and country rather than a single urban area.

History and culture are rich and varied: Roman Verulamium survives as archaeological parks and a museum around St Albans, while grand houses such as Hatfield House and Knebworth House reflect Tudor and later country-house traditions. The county also has a modern creative edge, with film and TV production centred around Leavesden and a lively programme of festivals, theatres and markets in towns large and small.

The economy mixes long-distance commuting to London with local industry, technology parks and service sectors, and good road and rail links via the M1, M25 and A1(M) and fast trains to the capital. Towns such as Watford, Stevenage and Hemel Hempstead each have distinct characters, while many smaller communities retain village life and agricultural roots, making the county socially diverse but generally popular with families and professionals seeking easy access to the city alongside countryside amenities.
