Slavery Remembrance Day, as designated by UNESCO, took place in Liverpool on 23 August 2007. The day was commemorated with a series of events, marked first by a multi-faith act of worship at Liverpool's Parish Church of St Nicholas. A traditional African libation ceremony, calling on ancestors to bless the event, took place on the city's waterfront at Otterspool Promenade. A programme of music and drama showcased Black culture and heritage around the themes of life in Africa, the Middle Passage and the legacies of transatlantic slavery. The International Slavery Museum at the Albert Dock had its official opening on the same day. The symbol of the day was the Sankofa, a mythical African bird that files forward while looking backward.
