Southwell ( or ) is a town in Nottinghamshire, England, best known as the site of Southwell Minster, the seat of the Church of England diocese that covers Nottinghamshire. Its population is about 6,900.
The origin of Southwell's name is not clear, but there a number of locations which claim to be the original "well", most notably at GR708535 where a plaque has been placed; in the Admiral Rodney public house; one on the south side of the minster which was called Lady Well in the 19th century; and one by the cloisters called Holy Well. Norwell (pronounced "Norrell") approximately eight miles northwest may support the notion of there being "south" and "north" wells in the area. The town lies on the River Greet, approximately 14 miles (22 km) northeast of Nottingham. In addition to the Minster (the cathedral and parish church of St Mary of Southwell), there are a number of other historic buildings in the town, notably the impressive prebendal houses along Church Street and Westgate, and the town's Methodist church has the unusual feature of an old right-of-way running underneath it, necessitating a larger upstairs than downstairs seating capacity.
