In 2007 Westminster City Council supported a programme of events in the libraries, galleries and archives of the area, including films, walks and exhibitions, designed to provide opportunities to learn about the culture of Westminster's communities. Highlights included guided heritage walks with historian S. I. Martin, exhibitions of images from the Royal Geographical Society in Paddington Library, Maida Vale Library and Westminster Reference Library, and film screenings (in partnership with 100 Black Men of London). A partnership between the City of Westminster Archives Centre, Tate Britain, Parliamentary Archives, National Gallery and National Portrait Gallery produced a heritage trail 'On the Road to Abolition: Ending the British Slave Trade', which takes in key sites, events and individuals in Westminster relating to the slave trade, between Trafalgar Square and Pimlico. In celebration of Black History Month, Westminster City Council produced a booklet, 'Black History in Westminster', detailing some of the borough's influential Black residents.
