Pikworo operated at the intersection of local power and transatlantic demand. Captives -- taken in raids and conflicts across the Sahel -- were brought south to this rocky outcrop about three kilometers west of Paga, in what is now Ghana's Upper East Region. Here, Ghanaian traders gathered them for sale to agents representing the French, English, and Dutch. At any given time, approximately two hundred people were held at the camp, confined among the boulders with minimal shelter. The landscape itself functioned as both prison and marketplace. A prominent gash in a large rock served as the captors' water source, while the enslaved carved their own eating bowls from the surrounding granite -- the size of each hollow corresponding to the number of people forced to share it.

When enough captives had been assembled, the march began. Two to three months on foot, roughly 150 kilometers south to the slave market at Salaga, then onward through Bono Manso and Assin Manso to the coastal forts at Cape Coast and Elmina. The enslaved walked barefoot and barely clothed while their captors rode horses. Salaga, one of the largest slave markets in West Africa's interior, served as the pivot point -- a place where people were resold, revalued, and redirected toward the waiting ships. The route from Pikworo to the Atlantic coast traced a corridor of suffering that connected the deep interior of the continent to the global economy of forced labor.

Today Pikworo is a memorial site, its granite boulders unchanged since the camp's abandonment after abolition in the mid-nineteenth century. Local guides lead visitors through the rock formations, pointing out the carved eating bowls, the water gash, the flat stones where captives were displayed for auction. The physical evidence is modest -- no walls, no chains, no architecture -- but its modesty makes it more unsettling, not less. These were people held in the open, controlled by violence and the sheer distance of empty savanna surrounding them. As guide James Suran-Era has noted, the moment slavery was abolished in Europe, people immediately ran away. They had always known what awaited them.

Pikworo exists in a landscape where the past is carried orally rather than archived. There are no plaques from the eighteenth century, no colonial records of the camp's daily operations. What survives is the rock itself and the stories passed down through generations in Paga Nania. Visitors -- many of them from the African diaspora -- come to Pikworo as part of heritage tourism routes that also include the sacred crocodile ponds of Paga and the coastal slave forts hundreds of kilometers to the south. Standing among the boulders, the connection between this quiet inland site and the vast Atlantic crossing becomes visceral. The camp is a reminder that the transatlantic slave trade was not only a coastal phenomenon. Its roots reached deep into the continental interior, and the evidence of that reach is written in stone.
