Introduction This research explores the secondary depositions (SD) of human remains (HR) identified in Carmo cemetery (fig. 1-3). This site operated during a period marked by war and pan/epidemic disease in Porto (1801-1869). Data & Methodological Approach SD are defined as clusters of HR resulting from disturbances after primary burial. SD were classified based on location, bone dispersal, and spatial/stratigraphic patterns. “PIECING TOGETHER PAST STORIES”: COMMINGLED HUMAN REMAINS FROM THE CEMETERY OF THE THIRD ORDER OF OUR LADY OF CARMO (PORTO, PORTUGAL) Figure 1: Location of Porto on th e map of Portugal.

Acknowledgments We would like to acknowledge the people whose remains we have the privilege to study and care for, without whom this work would no t be possible. We would also like to thank all the members of the fie ld and laboratory work team, in particular Rodry Mendonça for his h elp with processing the photogrammetry and orthophoto data. SD: A lens for Understanding Past Populations This study shows the diversity of SD identified. Their analysis can provide insights into site formation dynamics and sheds light on human behaviour, social interactions, and cultural practices.
