How do Indigenous repertoires of ‘care’–i.e. scripted and ad hoc practices of using, maintaining, repairing, and beautifying religious sites and objects–intersect with the ‘work’ of historical conservation? In what ways are religious values expressed through the continued use and reuse of historical sites? Finally, can these works of piety be integrated within current conversations around the preservation of ancient temples and religious sites in Southeast Asia? To explore these questions, this essay brings images collected during field research in 2023 at premodern Hindu and Buddhist temple sites in Cambodia into conversation with historical sources that contextualize the reciprocal relationships that exist between religious practitioners, sites, and objects.
