The article explores the archaeological site of Santa Coloma d'Ager in northeastern Iberia, active from the 5th to the 11th century AD. Initially, the site featured a church and accompanying cemetery for Christian burials. Archaeological excavations have revealed various burial structures, such as sarcophagi, cyst graves, and slab graves, indicating consistent Christian burial practices despite the region's eventual incorporation into Muslim Al-Andalus. The study incorporates anthropological, paleopathological, and dietary analyses of 107 skeletons, suggesting no unusual mortality patterns or evidence of interpersonal violence. Physiological stress markers indicate some nutritional hardships, aligning with regional agricultural practices. Isotopic analyses reveal a reliance on C3 plant diets and limited animal protein, reflecting the community's rural lifestyle. Overall, the findings illustrate the resilience and continuity of the Mozarab community throughout significant historical upheavals until the 11th century, when the necropolis ceased functioning after the Christian conquest.
