Abbey ruins, Bury St Edmunds, Suffolk, England. Here at Bury St Edmunds the misrule of King John was such that the barons came together in the Abbey Church and plotted to extract concessions from the King. On November 20th 1214 Cardinal Langton and twenty-five barons swore an oath to make King John accept these conditions, enshrined in the first ever documented Bill of Rights, the Magna Carta. The Abbey was sacked by local towns people in 1327 and then on the 20th January 1465, a great fire ravaged the Abbey. It destroyed all the roofs, and brought down the central tower and spire.
