The destruction of St Mel’s Cathedral by fire brought the local community together to fund its restoration. Part of this initiative was the development of a lighting scheme using modern LEDs and intelligent lighting controls to recreate the atmosphere and reverence deserving of this historic house of worship. Problems encountered associated with the age and style of the building to be illuminated are discussed in the paper. A description of the design process and methodology is also included, along with the appropriate lighting conditions necessary to emphasize certain architectural points. The paper covers the illumination of the cathedral for the 21st century by discussion of the methods used and the development of the design.
