In the hush at the northern fringe of Taitung—where paddies hesitate before the city—Justus Dahinden’s Chapel Building commands a quiet rupture in the quotidian: a “simple rectangular prism, its walls cast in béton brut.”

Here, the unadorned surface of raw concrete becomes a canvas of atmospheric tension, the materiality itself speaking. The visceral layering of rainwater outlets, the rigour of shade‑casting fins, the irregular rectangular apertures beside the spiral stair—not window-nonsense, but purposeful disruptions—frame the outside world with a dialectical rhythm of rationalism and poetic gesture.

This is not ornament: it is a modulation of light, silence, solidity. Dahinden’s collaborators, notably engineer Dr. Schubiger, pushed a bold structural solution—a beam‑less slab system—that mitigated local material constraints, streamlining construction while halving rebar demands. In austere Taitung, that innovation is as much conceptual as structural—a refusal of limitation by way of ingenious formal economy.

By day, the lower three floors operate under modernist functionalist logic—classrooms, dormitories, workshops, a canteen—nods to “utility, economy, and clarity of plan.” And above, the chapel: a disciplined austerity animated only when colored‑glass Stations of the Cross catch sun rays, “patches of colored luminosity” vibrating across wooden pews, interrupting brut’s severity with an ephemeral candescence. In these moments, the building breathes, and the light becomes a liturgy in itself.

This hybridity—between brutalist muscularity and hushed devotional poetry—totally repositions Dahinden’s Chapel. It is a humbleised architectural echo of Ronchamp or La Tourette, yet absolutely anchored in Taiwanese soil. The material palette—exposed concrete, wood, and stained glass—anchors the building in both global spiritual‑modernist lineage and local geography. It doesn’t mimic; it translates.

Earthquakes in 1999 and 2003 endangered the structure, rendering it “dangerous” in official terms. But this building persisted—recognition followed: historic registration, restoration fueled by alumni donations (2004–2010), and eventual reincorporation into community ritual. This trajectory—from modernist ambition through seismic trial to civic resurrection—imbues the Chapel with a narrative as textured as its façade.

Now sometimes dubbed “The Notre‑Dame‑du‑Haut of Taiwan,” it resists the glamour of pilgrimage cliché. It does not tower theatrically; it confronts daily life: students crossing its threshold, the afternoon light slicing through colored glass, the concrete cooling under evening shadows. Its radical quiet asserts something urgent: that modernist architecture—with its insistence on clarity, material truth, and light—can still recalibrate our sense of the sacred in the everyday. In Taitung’s modest grid, this Chapel remains a vaulted pulse of architectural poetics, veiled in plain structure yet infinitely awakening.
