The Colombian institute of anthropology, which has a station in San Agustin, is at present taking care of and watching the area where the principal archaeological sites, mounds, funeral temples, tombs and statues are located.
In the administration house there is a library and museum open to the public where the visitor can broaden his knowledge of the culture of the ancient sculptors.
Following the Reichel – Dolmatoff Stylistic Classification (1972, p. 69) four principal styles can be observed:
The NATURALIST, where the forms represented are natural with no alteration in their basic characteristics. This group appears as one of the earliest in San Agustín perhaps contemporary with ARCHAIC style, a designation which seems most appropriate for the roughly worked stones. The more elaborate tridimensional forms correspond to the EXPRESSIONIST style, generally associated with the theme of the jaguar, the symbol of vital force. Finally, the so called ABSTRACT style deals with fantastic themes, and has a similar sculptural quality to the expressionist carvings.
