The Flag Fen centre and surrounding archaeological site
|Type||Archaeological open air museum|
Flag Fen, south-east of Peterborough, England, is a Bronze Age site comprising over 60,000 timbers, arranged in five very long rows, creating a wooden causeway, (around 1 km long), across the wet fenland. Part way across the structure, a small island was formed, where it is presumed religious ceremonies occurred. Archaeological work began at the site, which is located 800m (0.5 miles) east of Fengate, in 1982.
A Neolithic trackway once ran across, what archaeologists have termed, the "Flag Fen Basin", from a dryland area known as Fengate, to a natural clay island called Northey, (now the site of Whittlesey). The basin is an embayment of low-lying land on the western margins of the Fens, and, the level of inundation by 1300 B.C., led to the construction of a timber causeway along the trackway route.
The causeway, and center platform, were formed by driving 'thousands of posts with long pencil-like tips' through the 'accumulating peaty muds' and into the firmer ground below. The resulting structure covered three and a half acres. Dendrochronological analysis, or dating of the posts by studying tree rings, led to an estimated date for the various stages of construction of between 1365–967 BC.
Some of the timbers, such as oak, were not natural to the local environment. This means that the people who constructed this timber causeway wanted to use materials that perhaps had religious significance to their lives, and felt that it was worth the effort to transport the timbers from far lying sources to the site itself. This isn't rare in the prehistoric world, as the bluestones from Stonehenge were brought to the site in Salisbury from the Preseli Mountains in Wales.
Many items denoting 'rank and prestige' were deposited in the surrounding water of Flag Fen, including swords, spearheads, 'gold earings, tiny pins and brooches'. Archaeologist Francis Pryor, who discovered the site, suggests that 'settlers often vied for social status by showing they could afford to discard valuable possessions'. There is also evidence of intentional destruction before placement, e.g., daggers broken in half placed on top of each other.
Other finds included small, polished, white stones of a type not known in the area, indicating that they had been intentionally collected, transported to, and placed at the site. Significance is also drawn from the discovery of the ritual deposits within thirty metres of the timber post line, and only on its southern boundary.
Other artefacts that were found comprised animal bones. Of these, horse mandibles were found. Horses were very valuable to the prehistoric people, as they provided a means of transport, and could supplement or replace man-power. They could be used to carry timbers, for example, over long distances.
On Northey Island, many round barrows, contemporary with Flag Fen, were found. These seemed to be constructed over the dwellings of 'chiefs'. Mike Parker Pearson refers to this as the "Land of the Dead", although there is evidence of farming, including sheep remains, contemporary with the site. Phosphate analysis reveals high concentrations of cremations in the barrows, in the form of satellite and secondary burials in the round barrows. This suggests that the primary burials may have been of chiefs, or socially powerful/respected people, and that some people may have paid to be buried close to the person they respected or followed.
In the 10th century BC the ground level was much lower than today, increasing around 1 mm (0.039 inches) per year as autumnal debris is added to the surface of the fens. By the early Roman period most of the structure was covered and preserved. The anaerobic conditions found in the waterlogged soil prevented the timbers and other wooden objects from rotting away.
The site was first discovered in 1982 when a team led by Francis Pryor carried out a survey of dykes in the area funded by English Heritage. Pryor told National Geographic (magazine), in 1992, he 'stumbled - literally - upon' Flag Fen 'when he tripped on a piece of wood lying in the bottom of a drainage ditch.'
Excavation commenced in the summer of 1984 and, by 1990, had revealed vertical and horizontal timbers, animal bones, a bronze dagger and other metal items and fragments, flint implements and 400 potsherds. Further finds included items imported from continental Europe and the oldest surviving wooden wheel found in England.
Extensive drainage of the surrounding area, which benefits agriculture, means that many of the timbers are drying out and are threatened with destruction. One section of poles is being preserved by replacing the cellulose in the wood with water-carried wax, impregnating the wood over the years. This technique is also being used to preserve Seahenge. Another preservation technique used for timbers found at the site is freeze drying.
In the visitor centre's preservation hall one section of the timbers is preserved in-situ and prevented from drying out by misting with water. Also at the site are reconstructions of two Bronze Age roundhouses and one from the Iron Age. There is also an exposed section of the Roman road known as the Fen Causeway which crosses the site and a reconstruction of a Prehistoric droveway.
In 1991 Pryor's first book about Flag Fen, entitled Flag Fen: Prehistoric Fenland Centre, was published as one of a series co-produced by English Heritage and B.T. Batsford. The final monograph on the site – entitled The Flag Fen Basin: Archaeology and environment of a Fenland Landscape – was published in 2001 as an English Heritage Archaeological Report. Pryor followed this with a third book on the site, published by Tempus in 2005; entitled Flag Fen: Life and Death of a Prehistoric Landscape, it represented what he considered to be a "major revision" of his 1991 work, for instance repudiating the earlier "lake village" concept that he had come to reject.
Fens Creek, two miles from Flag Fen, is also rich in archaeological finds. In 2013, eight Bronze Age boats were discovered there at Much Farm. Carbon-14 dating fixes their age about 1500BC. The boats had apparently been deliberately sunk, and the water and sediments preserved them.
