The password of the project was interaction. With nature, with light, with the elements and, consequently, with God. The chapel stands in the private estate of the Perrella family, which extends on a vast hilly area covered by woodland. The outside of the chapel is inspired by the shapes of surrounding nature: it has a curving line that rises gently from the main entrance, becoming vertical in the bell-tower. The shapes suggest the outline of a mountain, while they glorify the tension upwards, towards God.
The chapel has an elliptical structure. The main entrance faces West, and it is reached along a tree-lined avenue, with a secondary entrance facing East, protected by a strongly symbolic oak tree. There are numerous symbolic references in the work, starting from the use of water and light. The external shell, which is supported by a network of galvanised steel trusses and made to shine by an opaque covering of shaped sheet metal, rises up from the ground surface of the forecourt, emerging from a pool which prevents it from resting on the ground. A low window pane that runs all along the perimeter of the chapel guarantees visual contact with the water and projects the light reflected in the pool onto the inside walls. The use of natural light is an important element, which encourages interaction with the outside: a large glazed area symbolically links the main entrance to the sky, emphasising the building's luminosity and uncluttered lines.
Pininfarina also designed all the interior furnishings: the altar, the cross with the tabernacle, the stoup at the entrance and the baptismal font, the organ, the seats for the celebrants, the ambo and the lectern on the altar.
