Archaeological and ethnohistorical investigations in the south of the Colombian Plateau, in the Eastern Highlands, suggest that before European contact Guatavita was an important Muisca chiefdom—largely because of the prestige conferred by the presence of ceremonial centers in their territories, especially around the lakes in the hills surrounding the Guatavita-Guasca Valley. The fame of Lake Guatavita as the most important Muisca shrine was fueled by Spanish chronicles during the sixteenth and seventeenth centuries, which described it as the core of mass offering ceremonies or of lavish rituals for the chief's investiture, which fed both the story and the myth of El Dorado. This article presents the results of the archaeological survey done around the lake. The type and distribution of the material culture suggest that there was a shrine where small-scale ritual offerings took place, rather than conspicuous celebrations.
