During the nineteenth century, infrastructures of devotion and religious worship in Ireland changed dramatically. By 1900, the landscape was transformed by the presence of highly decorated, prominent church buildings. The many building projects of the Roman Catholic church were highly dependent on donations and fundraising. This essay explores the extent to which historical narratives, images, and ideas were used in order to motivate donations, and to develop a sense of community engagement with these new buildings as both symbols of past persecution overcome, and future spiritual glory. It explores sermons and speeches associated with new church building projects as sites for the performance of historiographical authority, and traces the emergence of key narratives of identity and memory, which were powerfully expressed through the spaces and architectural forms of the church buildings.
