Nigeria is home to many hidden historical treasures, and one of its most remarkable yet lesser-known wonders is the Sungbo Eredo, often referred to as the Great Wall of Ijebu Ode Kingdom. Located in the rainforests to the southwest of Ijebu Ode in Ogun State, this massive man-made structure stands as a testament to the ingenuity and craftsmanship of the Ijebu people between 800 and 1000 AD.

A Monument of Immense Scale
Sungbo Eredo is no ordinary wall. At 100 miles long and towering at 70 feet, this crimson earthen wall is a feat of ancient engineering. Stretching across the Ijebu Kingdom, it served as a defense mechanism for the kingdom, safeguarding it from external threats. However, the sheer size of the wall extends beyond defense—it covers an area so vast that the structure, approximately 16,000 kilometers long, blends into the surrounding rainforests, with some parts hidden under moss-covered patches. This remarkable network of walls reflects the grandeur of the Ijebu Kingdom in its heyday.
The Legend of Oloye Bilikisu Sungbo
The Sungbo Eredo is more than just a wall; it’s a symbol of the legacy of Oloye Bilikisu Sungbo, an Ijebu noblewoman after whom the structure was named. Local lore suggests that Sungbo was a revered matriarch, and some even speculate that she may be linked to the biblical Queen of Sheba. Though the exact details of her life remain shrouded in mystery, her connection to this magnificent structure highlights the important role women played in Ijebu society.
A UNESCO World Heritage Site
In recognition of its historical significance, Sungbo Eredo was designated a UNESCO World Heritage site on November 1, 1995. Yet, despite this international recognition, Sungbo Eredo remains largely unknown, even within Nigeria. Hidden within the rainforests and largely covered by nature’s elements, this ancient wall holds secrets yet to be fully explored by archaeologists and historians alike.
A Window into Nigeria’s Past
Visiting Sungbo Eredo is like stepping back in time. The wall not only reveals the incredible skills of the ancient builders but also offers insight into the socio-political organization of the Ijebu Kingdom. It tells the story of a people who valued security, strength, and innovation long before European contact or the trans-Atlantic trade.
A Call to Explore
Today, Sungbo Eredo stands as one of the largest monuments in Africa, yet it remains underappreciated. As Nigeria continues to embrace its rich cultural heritage, it is crucial to shine a light on this extraordinary historical gem. For history enthusiasts, travelers, and anyone passionate about Africa’s untold stories, Sungbo Eredo offers a unique and awe-inspiring experience.
Final Thoughts
The Great Wall of Ijebu Ode Kingdom is a powerful reminder of Nigeria’s rich history and the innovations of its ancient civilizations. Its story has the potential to inspire a deeper appreciation for Nigeria’s cultural heritage and historical significance on a global scale.
