Church of San Francesco d’Assisi al Fopponino, Milan, 1961–64. The main façade is embedded in a perforated detached screen that uninterruptedly envelopes the two flanking buildings overlooking the large inclined parvis. The iridescent ceramic cladding, made of light gray, smooth and diamond-point tiles, captures and reflects the sunlight, while hexagonal openings allow the sky to show through. Photo © Luca Rotondo.
