Borough Market invites visitors to celebrate its millennium with their footsteps.
At each entrance shoppers will walk through a different colour of eco-friendly wash-away paint.
As they walk around the market, they will leave behind thousands of interlacing footprints, creating a vast and rapidly evolving work of art.
“The work will beautifully represent all the millions of feet that have passed through the Market over the centuries - from William Shakespeare to Charlie Chaplin - as well as those that have yet to come,” says Keith Davis, Managing Director of Borough Market.
The process will be filmed from above to create a time-lapse video clip.
At the end of the day the paint will be washed away, taking the streets of the Market back to their original state.
Borough Market dates from the 11th century and moved to its present site in 1756.
