The San Bernardo Chapel is a small masterpiece. A sensitive dealing with the location, an imaginative engagement with the principle of church construction, an equally simple as well as diverse and impressive shape, and a concentrated reduction are combined to make this worship place extraordinary. The chapel is located in the Argentine Pampa, neither running water nor electricity is available at the site itself. Whereas the exterior of the building is bordered by straight surfaces, the interior is characterized by curved ones.
The interior, constructed with traditional craftsmanship, impresses due to the way the architect deals with light, which plays an essential role for Christianity. The aperture that opens to the west captures the light of the sun that one can see wandering along the wall. Two wooden poles are arranged on the gallery, one vertically, the other horizontally. The course of the sun, which projects the shadows of the two wooden poles as lines on the interior surface of the chapel, gradually brings these shadow lines together and lets them ultimately appear as a cross. For the architect this is a symbolization of the way Jesus went.
