Scholars of the new, suburban burial grounds constructed in the nineteenth century have long imagined a tension between the monumental and ephemeral in the design and use of these sites. Ephemerality, in this framing, challenges the permanence of the monumental both in the construction of intentionally temporary public monuments and when architectural features designed to endure are destroyed. Navigating through interdisciplinary methodologies, including practice theory and spatial analysis, this chapter illuminates pivotal moments in the evolution of San Juan's first general cemetery. From clashes between imperial projects and local implementations to midcentury conflicts and substantial 1860s redesigns, the narrative uncovers a dance between permanence and transience. Embracing overlooked sources, innovative techniques, and experiential engagement with material spaces beyond traditional archival approaches, this methodological journey enriches our comprehension of 19th-century burial practices. Providing a captivating lens for understanding meaning-making processes, the fusion of materiality and practice theory not only revolutionizes our understanding of historical actors' choices but also offers a methodological roadmap for researchers navigating the complexities of historical cemetery studies. This paper emphasizes the importance of blending traditional and unconventional strategies for a holistic understanding of spatial dynamics and cultural practices, contributing not only to the exploration of 19th-century burial practices but also to methodological advancements in historical research.
