A ceremonial metate estimated to be more than 2,000 years old was accidentally discovered in the backyard of a private residence in Poás, Alajuela. The homeowners reported the finding to the National Museum of Costa Rica, which then proceeded to verify and recover the artifact.

Experts from the museum’s Department of Anthropology and History traveled to the site and confirmed the piece is a “tripod metate with a hanging panel.” This type of artifact, crafted from volcanic stone, is characteristic of the period between 400 B.C. and 300 A.D. It is associated with both domestic use for grinding food and important ceremonial functions in the region’s pre-Columbian societies.

The artifact was found in a good state of preservation. National Museum archaeologist Laura Arias stated, “These discoveries in non-traditional contexts are vitally important, as they provide new information about the settlement patterns and daily life of the ancient populations of the Central Valley.”

The National Museum reminded the public that, under Law No. 6703 on National Archaeological Heritage, all such artifacts are state property. It urged the population to immediately contact the institution upon making any similar finds to ensure the proper recovery and preservation of the country’s cultural heritage.

The piece has been transported to the National Museum’s laboratories, where it will undergo more detailed studies before being registered and integrated into the national collections.
