Had read about the Sweet Track, but in the event more or less stumbled upon it went we visited Shapwick National Nature Reserve. Details of such trackways, created thousands of years ago, can be found here. The Sweet Track has been dated back to the spring of 3806 BC, so almost six thousand years ago.
The Avalon Marshes, of which Shapwick is part, are a wonderful example of how degraded environments can be restored to nature. odd to feel the sponginess of the earth underfoot – and roads hereabouts seem to undulate, which may be because of subsidence, or maybe cider drinking by the road-makers?
