They march in five long rows across what was once a freshwater basin east of Peterborough, a wooden causeway over a kilometre long, built and added to by people who left no writing and no names. They started construction around 1365 BC and stopped sometime after 967 BC: nearly four centuries of work, generation after generation extending the same line of timber across the same fen. Halfway along they made an artificial island. Into the water beside it they threw swords, spearheads, tiny gold earrings, brooches, and small polished white stones not local to the area, carried in from somewhere far enough that the journey itself was part of the offering. The Bronze Age ended. The Iron Age came. The peat closed over the timber, and by the early Roman period most of Flag Fen lay invisible beneath the ground.

The wood looked worked. Once they started looking, they kept finding more of it, in five long alignments running south-east to north-we...

Two kilometres south of Flag Fen lies Must Farm, a Bronze Age settlement of round houses on stilts that burned and collapsed into the river around 1000 BC. The fire preserved an astonishing amount of ordinary life: textiles, wooden bowls, fish in pottery jars, querns mid-grinding...

Photo credit User:Midnightblueowl, CC BY-SA 3.0. Flag Fen runs a visitor centre with reconstructed roundhouses, both Bronze and Iron Age. You can walk inside the smoky dark of a thatched conical building and understand, suddenly, why hearths sat in the centre. Wooden posts mark the surface line of the original causeway across t...

Flag Fen: The Slow Disappearance of Wet Ground

Wed, 27 May 2026 00:00:00 GMT

Photo credit User:Midnightblueowl, CC BY-SA 3.0. Flag Fen survives because the peat survived. When the fens were drained from the seventeenth century onwards, vast wetlands shrank back to ribbons and ditches, and the organic remains that the wet ground had preserved began to dry out and decay. Modern conservation pumps water ba...
