sweet track
A neolithic footway 2km long over marshy ground in Somerset, dating from about 3,800 BC. It was preserved in peat and named after Mr R. Sweet, who discovered it in 1970 following peat cutting. The track consists of riven planks of oak, ash and lime laid singly end to end and supported off the ground by pegs of hazel and alder.
