Spalding, a market-town of Lincolnshire on the river Welland, 34 miles S.E. of Lincoln, and in the heart of the Fens. It grew up after the Conquest about a famous priory, of which no traces exist. The parish church is a fine specimen of 13th-century Gothic, and the grammar school had its source in the desecrated Lady Chapel, but is now rebllilt on another site. The town depends for its prosperity on the surrounding agricultural district.
