Terrington St. Clement is a large village in Norfolk, England. It is situated in the drained marshlands to the south of The Wash, 7 miles west of King's Lynn, and 5 miles east of Sutton Bridge, Lincolnshire, on the old route of the A17 trunk road.
The parish covers an area of 45.38 square kilometres (17.52 sq mi). Much of the farm land is of alluvial silt and clay which has been reclaimed from the sea. This amounts to approximately half of the total parish area. In area it is the third largest civil parish in Norfolk. The population of Terrington St Clement has grown substantially and stood at 4125 in the UK census of 2011.
By the medieval period the small settlement which began on raised ground on the edge of the marsh had grown substantially. The magnificent Parish Church, dedicated to St Clement (i.e. Pope Clement I), known as the "Cathedral of the Marshland", was built in the 14th century by Edmund Gonville, Rector of Terrington, who founded Gonville Hall (now Gonville and Caius College) at Cambridge University.
Methodists arrived in the village in 1813 and during the Victorian era the Wesleyan Methodist Chapel and the Primitive Methodist Chapel were established along with a Salvation Army headquarters and 3 other mission chapels.
