The Architecture of Ritual

Last week, as 133 cardinals gathered in the Sistine Chapel to elect Pope Leo XIV—the first American pontiff—the architecture of the space served as much a part of the ritual as the centuries-old traditions themselves. Steeped in custom, the Conclave offered a compelling example of how formalized sequences—actions, settings, and objects—can embody enduring meaning. It demonstrated the deep intersection of architecture and ritual.
 
That intersection came into sharper focus following the recent release of Conclave, the 2024 film adaptation of Robert Harris’s novel. The film, which I greatly admired, portrayed the mechanisms of the papal election with attention to mood and space. Its quiet pacing and the solemnity of the setting—particularly the Sistine Chapel—conveyed how the ritual gained force not just from faith but from repetition, setting, and symbolism. This framework shaped how the real Conclave unfolded, and how it was perceived.
 
The process followed established procedure. The cardinal electors gathered in the Sistine Chapel on May 7. They stayed sequestered through the voting process, which culminated in a successful ballot the next day. Ballots were burned, as tradition prescribes, and white smoke signaled a decision. After accepting his election, the new pope spent time in the Room of Tears before emerging in papal vestments. His appearance on the loggia of St. Peter’s Basilica formally introduced him to the world as Pope Leo XIV.
 
Each step followed a fixed sequence, refined since the 13th century. These weren’t empty gestures. The acts of seclusion, voting, waiting, and revealing each served a purpose. Together they structured the transfer of authority and made it legible. The built environment of the Vatican shaped and amplified the process. The architecture didn't merely house the ritual; it framed it and gave it weight.
 
The Sistine Chapel played a leading role. Michelangelo’s frescoes, including The Last Judgment, surrounded the cardinals with images of divine judgment and salvation. The space, enclosed and richly symbolic, emphasized solemnity and introspection. It fostered deliberation by design, its scale and intimacy reinforcing the gravity of the decision.

In contrast, St. Peter’s Square staged the event’s public dimension. The crowd gathered there understood the signals. Dark smoke meant inconclusive voting. White smoke confirmed a result. The central balcony of the basilica offered a platform from which the new pope could be revealed, framed by the architecture as both figurehead and shepherd. The spatial sequence—from private deliberation to public appearance—mirrored the transition from selection to leadership.
 
Even the pope’s clothing choices communicated intent. Pope Leo XIV wore the red mozzetta—a shoulder cape that had fallen out of use under his predecessor, Pope Francis. That decision sparked interest because it suggested a return to visible expressions of papal tradition. Francis, in 2013, had declined the mozzetta to emphasize humility and discontinuity with a more monarchical style of papacy. By choosing to wear it, Leo XIV aligned himself with earlier precedent, not necessarily rejecting simplicity but reasserting the symbolic aspects of the office. Vesture, like ritual and architecture, helps define the papal role—not only for the faithful, but for the watching world.
 
Architecture outside religious contexts can function in similar ways. A courthouse, for example, may guide participants through security checkpoints, long corridors, and formal chambers, reinforcing the seriousness of the proceedings. A university campus might use a progression of quads, arcades, and lecture halls to communicate hierarchy, purpose, and community. These sequences don’t rely on belief; they rely on structure. When people move through spaces designed to mark transition, the experience becomes comprehensible.
 

"Habemus Papam"

Ritual and architecture also share a reliance on symbolism. In the Conclave, the white smoke became a decisive symbol, understood across languages and cultures. It gained this power through repetition and context. Likewise, in architecture, repeated formal cues—such as a threshold, a dome, or a columned portico—signal importance or transition. These cues don't need to be literal to be effective. They work because people have learned to recognize and interpret them.
 
Tradition persists not simply because of reverence for the past, but because it serves a practical function, reflecting patterns that have held meaning over time. When a procession follows a defined route, it creates order. When a ceremony unfolds in a particular place, it draws strength from continuity. These enduring forms—examples include the circular layouts of ancient gathering spaces or the thresholds marking transitions—demonstrate how physical design can give shape to shared experience. Architects who understand this can design spaces that support shared purposes, even in secular contexts. A civic plaza can invite assembly. A memorial can promote reflection. A council chamber can foster deliberation. The forms vary, but the intent remains: to shape human behavior and understanding through spatial design.
 
The Vatican illustrates how physical settings can support both timeless ritual and subtle change. The buildings remain constant even as each pope brings a different tone to the office. Leo XIV’s decision to embrace certain visual traditions doesn’t indicate a return to old hierarchies, but it does suggest an interest in reaffirming the symbolic weight of the role. Within the architectural and procedural framework of the Vatican, that kind of gesture has room to resonate.
 
The 2025 Conclave demonstrated how space, sequence, and symbolism work together to create meaning, even where disagreement exists. The Catholic Church includes a wide spectrum of views, yet the Conclave’s shared structure produced a clear, public outcome, offering a framework for moving forward despite differences. Though I am not religious, nor particularly spiritual, the event presented me with insights of broad relevance. In a time when many institutions face fragmentation, the deliberate use of ritual and architecture to foster clarity, continuity, and collective focus remains a powerful tool.
