Lincolnshire is a county in the east of England. It borders Norfolk, Cambridgeshire, Rutland, Leicestershire, Nottinghamshire, South Yorkshire, and the East Riding of Yorkshire. It also borders Northamptonshire for just 19 metres (20 yards), England's shortest county boundary. The county town is the city of Lincoln, where the county council has its headquarters.
The ceremonial county of Lincolnshire is composed of the non-metropolitan county of Lincolnshire and the area covered by the unitary authorities of North Lincolnshire and North-East Lincolnshire. The county is the second largest of the English counties and one that is predominantly agricultural in land use.
The county can be broken down into a number of geographical sub-regions including: the Lincolnshire Fens (south Lincolnshire), the Carrs (similar to the Fens but in north Lincolnshire), the Lincolnshire Wolds, and the industrial Humber Estuary and North Sea coast around Grimsby and Scunthorpe.
