Introduction: The Fen Causeway was the principal east/west route in the Roman period across the East Anglian Fens in the counties of Cambridgeshire and Norfolk. The road largely consists of a thick spread of sandy gravel, and takes an eccentric course for much of its length, frequently diverting from a straight route to take advantage of islands of solid ground dotted throughout the region. The Causeway branches out of a complex of roads lying north of the river Nene and the village of Castor (west of Peterborough), and heads east, until its course is lost beneath modern Peterborough. The road re-emerges as it crosses the Fengate complex, a substantial prehistoric and Roman0-British settlement, which may have been abandoned by the time of the road’s construction.
