Mary Slessor is buried on the hillside in Duke Town, not far from the Old Residency Museum. Her grave is a simple plot in a small cemetery, marked clearly and visited by Nigerians and foreign travellers alike — she remains genuinely revered in Calabar, not merely as a colonial figure but as someone who lived and fought for the Efik people on their own terms.
The memorial site includes a small museum covering her life and work, with photographs and personal artefacts. If you visit only one biographical memorial in Calabar, make it this one. Slessor's story is one of the genuinely remarkable missionary careers in African history — unconventional, radical for its time, and impossible to reduce to a simple narrative.
