The cultural criteria that guided the project was to give the visitor a kind of initiatory journey that leads them outside the urban environment, through the spaces of the Necropolis, highlighted by different lighting perceptions, to the tomb of St. Peter, which symbolically is at the heart of the homonymous Basilica and of Christianity.
At the end of this trip, which runs mainly along what was originally an open path highlighted by raking light and the moon, a change in color and direction of light occurs, prior to reaching the tomb which appears and is finally illuminated with ‘accent lighting’.
The sensitivity of the subject involves the lighting design of strong emotional valences that can only be achieved through interventions that use the primary observation of the spectral characteristics and the intensity of the sources.
The basic choices are:
1. the use of optical fibers to differentiate production elements from those of projection of light, so as to simplify maintenance operations, and solve the problems of thermal emissions in the environment of the Necropolis
2. the use of two types of light sources for optical fibers: incandescent lamps and metal halide lamps. The first with warm light used to illuminate the Mausoleums and spaces of the tomb of St. Peter, the second to make the light colder for those who were walking in the open air.
