In a dry field near the village of Wassu, rough red pillars of stone stand in rings, some barely knee-high, some taller than a man. Nobody knows exactly who raised them. They are part of one of the largest concentrations of stone circles anywhere on earth, and almost no visitor to The Gambia ever sees them.

Wassu is a long way from the beach, and it is not dramatic in the way Stonehenge is dramatic. But stand among these stones in the early morning, with the savannah quiet around you, and you are looking at more than a thousand years of West African history that has nothing to do with Europe.

A landscape of stones

The stone circles are not a single monument but a whole landscape. They are spread along the north side of the Gambia River in a band about 100 kilometres wide and 350 kilometres long, reaching deep into Senegal. UNESCO lists four groups as World Heritage, together holding 93 circles. Across the wider region there are more than a thousand such monuments: circles, single stones, burial mounds.

The pillars are cut from laterite, the iron-rich red stone that lies just under the soil in much of the region. Iron tools were used to quarry them, and that is part of the point. These circles are the work of societies who knew how to work iron, organise labour on a large scale and move heavy stones over distance. A typical circle has between 8 and 14 pillars, smoothly shaped, some cylindrical, some square, some with a flat or slightly rounded top.

Who built them, and why

The honest answer is that we know some things and not others.

• What we know: they were built gradually over many centuries, from roughly the 3rd century BC to the 16th century AD. Excavations have found burials beneath or beside many circles, together with iron weapons, ornaments and pottery. They were funerary monuments, places of the dead, and very probably of ritual.
• What is striking: some sites contain mass graves, perhaps from an epidemic or a battle. Others show signs that people were buried alive, possibly as sacrifices. At Sine Ngayène in Senegal, single burials suggest an earlier cemetery before the mass burials.
• What we don't know: exactly which peoples raised them, what language they spoke, or why this one stretch of river became the place to build them. Local tradition has its own explanations, and you will hear some at Wassu. Archaeology has not settled the question.

These are among the oldest monumental structures in this part of Africa, built by Africans for Africans, centuries before the first Portuguese ship entered the river.

The lyre stones

A few pillars are split at the top into a V shape, like a lyre or a forked stick. Archaeologists call them "lyre stones" or "bifid stones". Most stand at Wanar in Senegal. Ker Batch has the only known one in The Gambia. Their meaning is unknown. You will hear theories at the site, and some are lovely, but none is proven.

What you will see at Wassu

• several stone circles close together in a fenced area, with pillars of different heights
• a small museum explaining the excavations, the burials and the wider Senegambian landscape
• a guide from the site, who will walk you round and tell you the local stories
• the village of Wassu itself, on the north bank road

Locals sometimes leave small stones on top of the pillars as offerings or to make a wish. Watch, and ask before touching. To many people here these are still places of the ancestors, not just archaeology.

How to visit

Most visitors see Wassu as part of a two- or three-day trip upriver, staying at Janjanbureh or one of the lodges along the river. From Janjanbureh, cross to Lamin Koto on the north bank and drive about 22 km to Wassu. Kuntaur, the base for boat trips to the River Gambia National Park and its chimpanzee islands, is close by, so the two make a natural day together.

From the coast, the drive takes five to six hours or more on the south bank road, or via the north bank and the Senegambia Bridge. A day trip from the coast is possible but exhausting. Stay a night. More in getting around The Gambia.

Older than the forts

Most heritage tourism in West Africa is about the European centuries: the forts, the castles, the slave trade. Wassu is a reminder that the region's history runs far deeper. When the circles were begun, Rome was still a republic. When the last were raised, the Portuguese were just arriving on this river. In Ghana the same longer story is told at sites like the Nalerigu defence wall and the old trading towns of the north. See Ghana-Net.com and GhanaMuseums.com.
