The Tree of Forgetfulness | Ouidah: Where Identity Was Stolen

The Arithmetic of Erasure

The Tree of Forgetfulness—L'Arbre de l'Oubli—is perhaps the most psychologically chilling station on the Ouidah Slave Route. It stands at the 1.2-kilometer mark of the Slave Route, marking the transition point from the commercial zone of Place Chacha to the desolation of the coast. For the average visitor today, it presents as a modest monument near a large, leafy tree enclosed in a low stone wall. But for the estimated one million Africans who passed it between 1671 and 1865, this was a site of forced spiritual surgery.

Here, slave traders attempted something more ambitious than physical capture: they attempted to steal identity itself.

The Ritual of the Circles

The ritual was as precise as it was cruel. It was based on a calculated perversion of local Vodun numerology — borrowing the sacred to profane it.

• Men were forced to walk around the iroko tree nine times.
• Women were forced to walk around the tree seven times.
• Children, when their presence was acknowledged, were sometimes forced to circle five times.

In Vodun tradition, 9 is the number associated with masculine energy and the completion of a cycle — the full harvest, the closing of a journey. Seven is associated with feminine energy and the mystery of creation — the seven days of life's unfolding, the seven sacred waters. By forcing the captives to circle the tree these specific numbers of times, the slavers weren't simply exhausting them. They were attempting a cosmological heist: using the architecture of the captives' own belief system to collapse it from within.

The theory was simple: with each rotation, a layer of the person's past would dissolve. One lap for the name. One for the village. One for the sound of the mother's voice. One for the language of prayer. By the final lap, the captive was meant to arrive at the ships as tabula rasa — a blank slate, a unit of labor without history, without lineage, without gods. Ready to be renamed, branded, and sold on the other side.

The Psychology of the Void

Modern historians and psychologists who have analyzed this ritual note that it also had a purely mechanical dimension. Standing under the relentless equatorial sun, starved and dehydrated, shackled to dozens of other terrified people, the repetitive act of walking in circles creates a state of ritualistic dissociation — a trauma response that fragments coherent thought and memory.

The slavers understood this intuitively. They understood that a slave with a memory is a slave with a motivation to revolt. The man who remembered he was once a warrior-king of the Fon — or a Yoruba merchant, or a Hausa scholar — was the most dangerous person on a slave ship. The Tree of Forgetfulness was an attempt to murder the spirit before the body could be sold, to precede the physical crossing with a psychological one.

It failed.

The Botanical History

The original tree that witnessed these atrocities was a massive iroko (Milicia excelsa), a species held sacred by the local Xweda people long before the slave trade arrived. The iroko grows slowly, reaching enormous size over centuries, and is considered in many West African traditions to be inhabited by powerful spirits. The slavers chose it precisely because of its spiritual significance — the corruption of the sacred was the point.

In a final irony that history did not plan but the ancestors perhaps did, the original iroko died in the late 20th century, as if it could no longer hold the weight of what it had witnessed. The tree that stands at the monument today is a descendant, planted in the exact same earth.

Local oral tradition holds that the soil at this site is saturated with the memories of those who refused to let go — that the roots of the new tree grow into the memories of the old captives, feeding on their refusal to forget.

"They thought the tree would make us forget. But a tree grows upward because its roots go deep. Our roots were in the soil of Ouidah. You can make a man walk in circles, but you cannot make his blood stop singing the songs of his homeland." — Griot Hountondji, 2018

The Spiritual Counter-Measure: The Tree of Return

Recognizing the psychological damage being done, local Vodun priests and the captives themselves established a secret counter-ritual further along the route, near the beach.

They identified another tree — L'Arbre du Retour (The Tree of Return). This tree belonged entirely to the enslaved, not to their captors. Captives would walk around this second tree three times — the number of the soul's journey in Vodun cosmology, the three realms through which the spirit travels. The belief: even if their bodies perished in the strange lands across the sea, their souls would navigate under the Atlantic Ocean through the tree's root system and re-emerge in the Sacred Forest of King Kpassè in Ouidah.

This was not passive hope. It was an act of spiritual insurgency. It transformed the slavers' architecture of despair — the entire sequence from auction to ocean — into something the captives partially owned. The "No Return" became, for those who walked around the Tree of Return, a "Delayed Return."

Today, visitors tie white ribbons to the replacement tree. The ritual has never stopped.

Memory in the Diaspora

The legacy of the Tree of Forgetfulness is written across the entire diaspora. When a person from Chicago or Salvador da Bahia or Port-au-Prince takes a DNA test searching for their ethnic origins — when they seek their "Day Name" (Kofi for a Friday-born Akan man, Ama for a Saturday-born woman) — they are symbolically walking the nine circles in reverse. They are un-forgetting. One lap at a time.

The monument sculpture at the site today, titled "The Gate of Memory," shows faces emerging from the grain of wood and intertwining with roots — identities that were buried, not erased. Like dormant seeds, they waited for the right conditions to return to the light.

Visiting the Site Today

When you reach the 1.2-kilometer mark of the Slave Route, the road widens slightly. The monument is deceptively simple — a low-walled enclosure around the tree, a plaque, an invitation to stand still.

• What to do: Most visitors walk the circles in reverse — beginning at 9 and counting down to 1. It is a gesture of "Un-forgetting," a reclamation performed in the same space where forgetting was forced.
• What to observe: Look at the bark of the current iroko. It is frequently draped in white cloth by local families who come here for what they call "Memory Healings" — ceremonies for descendants who feel severed from their roots.
• The Atmosphere: This section of the road is uniquely quiet. The bustle of the city markets has faded behind you; the sound of the Atlantic has not yet reached you. You are, precisely, in the middle — the psychological "middle passage" of the walk, where the weight is most intense.
