On the 11th June 1144 Abbot Suger of the Abbey of St Denis, Paris, gathered the bishops of France for the dedication of his newly built choir and east end. This marked a sea-change in architecture, gone was the heavy solidarity of the Romanesque and in came the lightness and delicacy of the Gothic. In the years after the meeting of the bishops, many of their home cathedrals would burn down only to rise from the ashes in the new gothic style of Suger’s St Denis.
