These two buildings form the core of an atmospheric, heavenly adventure visible from the left bank of the river Saône. Conjuring up the flooding and storm of 1852, the chevets of the basilica and cathedral are attacked by lightning and rising floodwater respectively. With the lull in the storm, the sun and moon will appear and, in the unchanging cycle of day and night, will cloak the monuments and the hill with their glow which can be bright, soft or light and dark by turns. Using moving and spectacular staging, the show uncovers a hitherto unseen view of the hill situated between the heavens, the earth and the Saône. The artistic choice of lighting, the monumental moon structure and the large-scale stage effects sublimate the architecture of the Saint-Jean cathedral and the Fourvière basilica by giving them a whole new look.
