This document is a dissertation examining the use of ruins as war memorials, using Coventry Cathedral as a case study. It discusses how the ruins of Coventry Cathedral, destroyed in the Blitz, were preserved and incorporated into the new cathedral built after the war as a memorial. The architect Basil Spence designed the new cathedral to be "entwined and in dialogue" with the old ruins, creating a memorial that invites recollection of the Blitz in a spirit of peace rather than suffering. The document provides historical context on the bombing of Coventry and analyzes theories of collective memory and memorialization as they relate to the cathedral ruins.
