Driven back by water
Around 1000 BC the Bronze Age fields at Fengate were abandoned, probably as rising water swamped the woods and pastures. Through the Late Bronze Age and Early Iron Age, farming here was patchier. As the Fens settled, people returned.

Cat’s Water
Francis Pryor’s excavations uncovered a Late Iron Age village he called the Cat’s Water settlement. Forty-five structures were recorded, including 18 roundhouses. It may have been protected by rivers on two sides and widely spaced ditches on the third. Water remained a problem, and the site was abandoned around the time of the Roman conquest.

Offerings continue
Flag Fen stayed a special place long after the causeway was finished. Finds there include a complete but broken Iron Age sword of around 500–400 BC and a pair of shears still in their wooden case. The area sat between three peoples: the Catuvellauni to the south, the Corieltauvi to the north and the Iceni to the east.
