The Freedom Sculpture was conceived by Mary Thompson, a teacher at Dog Kennel Hill Primary School in East Dulwich, as a way for the school to mark the bicentenary. Year 6 pupils worked with Kevin Boys, a blacksmith from Surrey Docks City Farm, to translate their ideas of freedom into a visual image. A butterfly was chosen to represent the concept of freedom. Kevin Boys made the butterfly's wings on a mobile forge in the school playground, and Year 5 children designed patterns to place inside. The Freedom Sculpture was opened in the school grounds in November 2008 by Shami Chakrabarti of Liberty, the civil liberties advocacy group.
