church bells ring out the route of King John to Runnymede, to sign Magna Carta

There was bell ringing along the line of King John's progression from Odiham to Windsor and Runnymede.  Odiham ringers organised a ripple of ringing along the route King John may have taken.  The (church) towers along the way include Odiham, Rotherwick, Heckfield, Eversley, Yateley, Sandhurst, Hawley, Yorktown (Camberley), Bagshot, Egham, Old Windsor and Wraysbury.

The event marks the commemoration of 800 years since the signing of the Great Charter (Magna Carta)   King John was compelled to sign the charter after the citizens of London had opened the city to rebellious barons

Although conceived of as a bell-ringing occasion and not an art event, in fact this was very much a site-specific sound installation on a landscape scale. It follows an event that was very-much conceived as art (and publicity), the "Wall of Sound" , live music relay across Hadrian's Wall.
