Opened in 2007 within Liverpool's Royal Albert Dock, this is the only national museum in the world dedicated specifically to the history and ongoing legacies of the transatlantic slave trade. Liverpool's own wealth was built substantially on that trade: by the late 18th century the city's merchants controlled a large share of Britain's slaving voyages, and the museum confronts this local history directly alongside broader galleries on West African life before enslavement, the Middle Passage, and the slave trade's enduring legacies in racism and inequality today. A dedicated Campaign Zone gallery links this history to contemporary anti-slavery and human rights work. The museum closed for a major redevelopment in the mid-2020s, with reopening planned for 2028.
