Bells are currently ringing out across London and the UK to mark the start of the Olympic Games.
The bells will chime for three minutes as part of the London 2012 Festival commission All the Bells by Turner Prize-winning artist Marting Creed.
Thousands of people are taking part, from organisations including the Royal Navy, Army and the RAF, to churches and individuals.
People taking part are ringing all kinds of bells, from hand bells and doorbells to tower bells.
Ruth Mackenzie, director of the Cultural Olympiad and London 2012 Festival, said: “The commission shows the Festival’s commitment to world-class artists and to the values of participation.
“Martin Creed’s wonderful idea gets everyone involved in the opening day of the Games not just as an audience but as an integral part of the work.”
