[2][3] Central to the development of Horningsea as a settlement has been its location on the River Cam, whose use for navigation dates back to at least Roman times.Around 4000 years ago, the parish consisted of a chalk promontory between marshland and the sea, and there is evidence of Iron Age habitation.[4] Drainage of the area began with Bottisham Lode in early medieval times, and a bridge is mentioned in the village in the late 13th century.In 1637 the Earl of Bedford was given 400 acres in Fen Ditton, Horningsea, and Stow cum Quy which were drained over the following 20 years.[6] Horningsea has two pubs (the Plough and Fleece [7] and the Crown and Punchbowl[8]), and the parish church of St Peter.
