Lincoln, England up to above sea level in the uphill area around the cathedral. Lincoln is situated at an elevation of above sea level, in a gap in the Lincoln Cliff (a major escarpment that runs north–south through Lindsey and Kesteven, in central Lincolnshire and rises to an altitude of in height). The city lies on the River Witham, which flows through this gap. Lincoln is thus divided informally into two zones, known unofficially as uphill and downhill, with uphill at above sea level in the area near Lincoln Cathedral, and downhill at above sea level, by the River Witham. The uphill
