A model of St Paul's made entirely from the packaging of fairtrade products was unveiled in the famous cathedral on Monday for Fairtrade Fortnight.
The unveiling was joined by Fairtrade sugar producer Henry Matenga, from Malawi, and Sophi Tranchell, managing director of Divine Chocolate company.
It comes as the Diocese of London celebrates its first anniversary as an accredited Fairtrade Diocese.
The model was designed and created by Amanda Hughes, Children's Church Co-ordinator of St Mary's, Finchley, to celebrate the London Diocese's support for fairtrade.
"I'm thrilled to see the model in St Paul's Cathedral and feel very happy to do my small part in showing how we can help reduce poverty in the world with our shopping habits," she said.
The eight-feet long structure is made up of fairtrade chocolate wrappers, tea boxes, and even banana stickers.
It symbolises the unity of the Diocese in its fairtrade mission, with the model railings surrounding the Cathedral highlighting the names of all 237 Anglican churches within the Diocese of London that have a Fairtrade certificate.
Canon Precentor of St Paul's Cathedral, Michael Hampel, said: "St Paul's are very happy to provide a temporary home for this wonderful sculpture during Fairtrade Fortnight."
The sculpture will be on display by the west doors of St Paul's Cathedral for public viewing until 10 March.
