The Bedford Level experiment was a series of observations carried out along a 6-mile (10 km) length of the Old Bedford River on the Bedford Level of the Cambridgeshire Fens in the United Kingdom. They were performed during the 19th and early 20th centuries to deny the curvature of the Earth through measurement.
