The archaeological site San Pedro, located in the area of influence of Rabón stream in Depresión Momposina is one of the best preserved places of the region. Plazas and Falchetti identified during the nineteen seventies, a complex system of channels and ridges that surround a large area of platforms located towards a central village. On the outside of channels and ridges, large sets of platforms are also identified, this time with artificial hills that seem to correspond with burial mounds. This site dated 680 (± 120) AD, is part the first evidence of occupation in the region. In this article, we discuss the spatial analysis of the architectural setting of these sites, and the differences among them. https://doi.org/10.22380/2539472X24
