Borough Market staff and traders were joined by Cultural Olympiad boss Ruth Mackenzie on Thursday to rehearse for Martin Creed's 'All the Bells' event which will mark the start of the Olympic Games.
At 8.12am on Friday 27 July thousands of people across the UK will join together to ring bells and welcome the games.
Work No.1197: All the bells in a country rung as quickly and as loudly as possible for three minutes by Turner Prize winner Martin Creed is part of the Cultural Olympiad and Borough Market is inviting customers to join traders in the Green Market to ring as many bells as possible for three minutes.
Traditionally, a bell was rung to mark the start of the day's trading at Borough Market.
"Borough Market is delighted to be taking part in such a great project and I can think of no better way to mark the start of a unique summer for London when the market will be open seven days a week throughout the Olympic and Paralympic Games.
"So why not grab a bell and join us under the railway arches of the Green Market to ring in the games?"
Traders including Bread Ahead and Flat Cap Coffee will be on hand ready to serve croissants, baked goods and coffee for breakfast.
The NT will be ringing the giant bell from Danny Boyle's production of Frankenstein on the Baylis Terrace and would like all its neighbours and friends to join them for coffee and pastries in sight and sound of some of the great bells of London.
Visitors will be able to have a go at ringing the Frankenstein bell themselves.
