Costa Rica's indigenous peoples don't get the visibility of those in Guatemala or Mexico, probably because they number only 40,000 out of a population of 4 million. This museum, part of the Centro Neotrópico Sarapiquís, provides a well-rounded all-under-one-roof introduction to the subject. Nearly 400 artifacts of the Boruca, Bribri, Cabécar, Guaymí, and Maleku peoples are displayed, including masks, musical instruments, and shamanic healing sticks. Start by watching a 17-minute video introduction, Man and Nature in Pre-Columbian Costa Rica. A botanical garden next door cultivates medicinal plants still used by many traditional groups. In 1999 researchers discovered an archaeological site on the grounds that contains pre-Columbian tombs and petroglyphs dating from the 15th century. The site is still under study.
