Tube art depicts imaginary travel

Giant artworks at London Underground stations aim to take passengers on a journey "to the centre of the Earth".

Artist Gayle Chong Kwan has covered walls at Southwark and London Bridge Tube stations with three artworks.

She worked with local market traders and restaurant staff to create the works, on themes of imaginary travel and the Underground's culinary history.

Part of London Underground's Platform for Art public art programme, they will be on display until May 2008.

Ms Chong Kwan said: "I wanted to recognise the fantastical nature of travelling underground, as well as recognising the culinary aspects of the Underground and how it was used to transport food to people sheltering there during the Second World War."

Last week artist Brian Griffiths unveiled a giant panda head, a caravan and a heap of sand in Gloucester Road Tube station as part of his installation, entitled Life is a Laugh.
