Modern religious architecture converses with a broad spectrum of social, anthropological, cultural and theological discourses and the authors engage with them rigorously and innovatively. As such, new readings of sacred spaces offer new angles and perspectives on some of the dominant narratives of the nineteenth, twentieth and twenty-first centuries: empire, urban expansion, pluralism and modernity. In a post-traditional landscape, religious architecture suggests expansive ways of exploring themes including nostalgia and revivalism; engineering and technological innovation; prayer and spiritual experimentation; and the beauty of holiness for a brave new world. Shaped by the tensions and anxieties of the modern era and powerfully expressed in the space and material culture of faith, the architecture presented here creates a set of new turning points in the history of the built environment.
