A vast system of ditches and ramparts enclosing the Ijebu kingdom, now largely swallowed by forest.

Why it matters

One of the largest known pre-mechanical earthworks in Africa, enclosing the historic Ijebu kingdom in ditch and rampart.

History

Local tradition associates the earthwork with Bilikisu Sungbo, a wealthy woman remembered in Ijebu oral history, whose shrine at Oke-Eiri draws pilgrims. Archaeological survey work in the 1990s recorded the scale of the system and proposed a first-millennium construction date; the association with Sungbo herself is traditional rather than archaeologically demonstrated.

Travel guidance

Responsible travel

The banks erode easily. Walk with a community guide, keep to existing paths, and do not dig.

Visitors should follow local guidance and community protocols. Do not enter restricted sacred areas, remove artefacts, disturb wildlife or damage archaeological remains.
