A series of Formative Period causeways (sacbeob) at the Maya site of Yaxuná, Yucatán, Mexico, constituted elements of an early geomantic plan that was renegotiated by the inhabitants of this centre for 1500–2000 years. This plan embodied a series of sacred metaphors including the World Tree and Milky Way. After its initial construction, this widely recognized sacred landscape was reinterpreted using the language of causeways and buildings by people with competing interests. A consideration of how the geomantic plan was differentially modified sheds light on important social transitions throughout the history of the site, as well as the role of landscape and shared memory among the ancient Yucatec Maya of Yaxuná.
