Lincoln is a cathedral city and the county town of Lincolnshire, within the East Midlands of England.
Lincoln developed from the Roman town of Lindum Colonia, which developed from an Iron Age settlement. Lincoln's major landmarks are Lincoln Cathedral, a fine example of English Gothic architecture, and Lincoln Castle, an 11th-century Norman castle. The city is also home to the University of Lincoln and Bishop Grosseteste University. Lincoln is situated in a gap in the Lincoln Cliff 141 miles (227 kilometres) north of London, at an elevation of 20.4 metres (66.9 feet) above sea level by the River Witham, stretching up to 75 metres (246.1 feet) above sea level in the uphill area around the cathedral.
