Sungbo's Eredo is Africa's largest construction, a 160km/99mi-long, 1050-year-old, 20m/65ft-high linear boundary rampart that once surrounded the ancient kingdom of Ijebu. Built over two centuries, it's now largely covered by rainforest; use the guiding services of locals to explore it, and respect the shrines and other crumbling remnants.
