Sweet Track

Listen for a moment. Reeds rustle in the wind, water drips somewhere in the ditches, and a bird calls from deep in the marsh. The ground here is soft and dark, made of peat that has built up over thousands of years. Somewhere below your feet, sealed in that wet blackness, lies one of the oldest timber walkways ever found in Britain. You cannot see most of it. That is exactly why it has survived.

This is the Sweet Track. It is a raised footpath of wood, built by Neolithic farmers. The Neolithic is the New Stone Age, when people in Britain first began to farm, keep animals and make pottery. The track once crossed a wide reed swamp in the Somerset Levels. It ran for roughly two kilometres, linking higher dry ground to a low island of land in the wetland. It gave people a safe way across water and mud that would otherwise swallow a careless step.

The name has nothing to do with sugar. In 1970, a peat cutter named Ray Sweet was digging in the drainage ditches here. Peat was a valuable fuel and garden product, and commercial cutting was common across these levels. Sweet noticed old pieces of worked wood in the peat face and reported them. Archaeologists soon understood the importance of his find. The track carries his name to this day, a small honour for a sharp-eyed working man.

Here is the first surprise. We know when this track was built with remarkable precision. Wood grows a new ring every year, and the pattern of thick and thin rings records the weather of each season. By matching these patterns against long reference sequences, scientists date timber very closely. This method is called dendrochronology. It shows that the trees for the Sweet Track were felled in the winter of 3807 to 3806 BCE. That is nearly six thousand years ago, measured almost to the season.

Think about what that means. The people who built this walkway lived long before Stonehenge took its famous shape. They lived before writing reached Britain, and long before metal tools. Yet here we know the very season they cut their trees. Few prehistoric sites anywhere give us that kind of exactness. It turns the Sweet Track into a fixed point in time, a single winter we can name.

The design is simple and clever. Builders drove long pegs into the soft peat at an angle, crossing them in pairs to make an X shape. Long poles lay along the ground beneath these crosses. Then planks were set on top, held in the notch where the pegs crossed. The result was a narrow plank walkway, raised just above the water. Several types of wood were used, including oak, ash and lime for the planks, with hazel and alder among the pegs.

The builders clearly understood their woodland. They chose different trees for different jobs. The quality of the split planks shows real skill with stone axes and wooden wedges. And this was not their first attempt. Beneath parts of the Sweet Track lies an even older walkway, now called the Post Track. Its timbers date to a few decades earlier. So people were crossing this marsh, and improving their route, for generations.

Here is the second surprise. The Sweet Track seems to have been used for only a short time, perhaps around ten years. Rising water and growing peat slowly covered it. The wood sank into a world without oxygen. That airless, waterlogged peat stopped the decay that normally destroys timber. And so the planks, pegs and the objects people dropped along the path stayed preserved, almost untouched, for thousands of years.

Those objects tell human stories. Excavators found flint tools, arrowheads, pottery and wooden bowls beside the track. Some pots still held traces of food, including hazelnuts. One find stands out above all. It was a polished axe head of jadeitite, a hard green stone. Studies trace this kind of stone to the Alps, hundreds of kilometres away across the sea. It shows no sign of use. Perhaps it was a precious gift, or an offering, carefully placed by the water.

That axe changes how we picture these people. They were not isolated. Valuable objects travelled across Europe, passed from hand to hand over great distances. A farmer walking this plank path may have carried knowledge, trade and beliefs linked to communities far beyond Somerset. Some of the finds, and lifted sections of the track itself, are now held in national museum collections, including the British Museum in London.

Most of the Sweet Track, though, is still in the ground. Draining and drying the land is the greatest danger, because dry peat lets oxygen reach the old wood. Today the area is part of a protected nature reserve. Conservation teams work to keep the water level high, and in places water is actively managed to keep the timbers wet. Out here, protecting the wetland and protecting the archaeology are the same task.

That wetland is full of life. The old peat workings have flooded into lakes, reed beds and wet woodland. Herons and egrets stand in the shallows. In spring you may hear the deep, booming call of the bittern, a shy marsh bird. On winter evenings, huge flocks of starlings often gather over these levels before they settle to roost. Look to the horizon, too. On a clear day, the steep shape of Glastonbury Tor rises above the flat land.

As you stand here now, look down at the path and the dark water beside it. Nearly six thousand years ago, someone stepped carefully along wet planks in this same marsh, perhaps carrying a pot of hazelnuts or a polished green axe. The reeds moved then as they move now. When you walk on, listen to the soft ground under your boots. The past here is not gone. It is simply resting, quietly, just below the surface.
