Docomomo Ontario is pleased to highlight the recent awarding of the Prix du XXe Siècle to the Ontario Science Centre, an honour that recognizes not only an outstanding work of modern architecture, but a profoundly Canadian idea of building with the land. Conceived in the cultural momentum of the Centennial era, the Science Centre belongs to the lineage of projects that sought to make public institutions optimistic, accessible, and future-facing. Here, that ambition is inseparable from its ravine setting: rather than dominate the site, the building is nestled into it, stepping with the topography and linking its pavilions by bridges and terraces that choreograph arrival, movement, and views through the Don Valley.
Architecturally, the Ontario Science Centre is distinguished by its muscular concrete expression, long spans, and crisp, pragmatic detailing, qualities that pair the confidence of late-modern construction with an unusually humane, experiential plan. Its sectional complexity turns circulation into discovery: ramps, stairs, and suspended walkways stitch together a sequence of galleries and outlooks, while controlled daylight and robust materiality reinforce a sense of permanence. As a seminal early work of Moriyama and Teshima Architects, the project announces themes that would recur throughout the firm’s practice, landscape as generator, public space as connective tissue, and architecture as an instrument for learning, making the Prix du XXe Siècle an especially fitting acknowledgment of its enduring cultural and architectural significance.
Yet the Science Centre’s future remains uncertain. Whatever its next chapter, this landmark has shown an enduring ability to serve and stay relevant to the surrounding community, even as its use evolves. The Prix du XXe Siècle recognition reinforces why its architectural and cultural value must remain central to any decisions ahead.
