San Agustín Archaeological Park

Stone guardians of the dead, some 600 of them, high in the Colombian Andes

San Agustín lies in the upper Magdalena valley of Huila, in the Colombian Massif where the three Andean ranges of Colombia split apart, about 520 km from Bogotá. Ancient remains are scattered over more than 300 square km of plateaus on both sides of the young river's canyon, and they make up the largest group of religious monuments and megalithic sculpture in Latin America, often called the largest necropolis in the world.

The people who made them lived in chiefdoms that took shape here from around 1000 BC, among the earliest complex societies in the Americas. In the Regional Classic period, roughly AD 1 to 900, they raised earthen burial mounds up to 30 m across over stone tombs for their leaders, with corridors, columns and monolithic sarcophagi, and set great carved guardians at the entrances. The biggest of these figures stand more than 4 m tall and weigh several tonnes, cut from tuff and volcanic rock. They mix human and animal features, jaguars, bats and crocodiles among them, on short legs, and they were once painted yellow, red, black and white; a few still carry colour. Snakes, frogs and birds keep watch over the bigger mounds. The dating of individual statues is uncertain, and much of the ground has never been excavated.

Of the 600 or so statues known across the region, about a third stand inside the park, along with half of the 40 monumental burial mounds. The Mesitas hold the oldest and largest tombs and the remains of the elite families who built them. At the Fuente de Lavapatas, figures and channels are carved into the bed of a stream. Outlying sites near Isnos complete the park: the Alto de los Ídolos, with the tallest statue of all at 7 m, and the Alto de las Piedras, home of the double-figured Doble Yo.

The ceremonial centres were abandoned around 1350. A Spanish friar, Juan de Santa Gertrudis, passed through in 1756 and described the statues in his Maravillas de la naturaleza, and the 18th and 19th centuries brought treasure hunters who broke into most of the tombs and found little. In 1913 the German ethnologist Konrad Theodor Preuss excavated for the Ethnological Museum of Berlin and later took 21 smaller sculptures there, and in 2022 Colombia formally asked the Humboldt Forum to return them.

Colombia created the park by law in 1931, together with its national archaeological service, and UNESCO listed it in 1995. Digging without a licence from the national institute ICANH is prohibited.
