Designed by Chicago-based architect John Ronan, Christ the King's 94,000-square-foot exterior is a pulsating pattern of fiber-reinforced cement panels in varying sizes, finishes and shades of gray, lending the building a strong visual identity using a relatively inexpensive product. At the easternmost end of the building, the rhythm of these panels is disrupted by another humble material, glass block, which also appears here in an array of sizes to form an intricate patterned wall containing the translucent Chapel of St. Ignatius Loyola within.
