The Calabar Slave History Museum, located in the historic Old Residency building, preserves the painful memory of Calabar's role in the transatlantic slave trade. From the 15th to 19th centuries, Calabar (Old Calabar) was a major departure point for enslaved Africans bound for the Americas. The Efik and Ibibio peoples, initially trading partners with Europeans, later became victims as the trade intensified. The museum displays shackles, chains, documents, and artifacts documenting this dark period. Marina Resort Beach nearby marks where enslaved people were held before being shipped across the Atlantic. The museum doesn't shy from this history; instead, it confronts it honestly, educating visitors about slavery's brutality and its lasting impacts. Archaeological excavations continue uncovering evidence of this trade. The museum participates in UNESCO's Slave Route Project, connecting African, Caribbean, and American descendants to their ancestral origins. Annual commemorations bring together diaspora Africans seeking roots. Calabar Museum reminds Nigeria that remembering painful history is essential for healing and ensuring such atrocities never recur.
