In the mango-color Bellavista Fortress, which dates from 1870, the museum gives you a quick and insightful lesson in English and Spanish on Costa Rican culture from pre-Columbian times to the present. Cases display pre-Columbian artifacts, period dress, colonial furniture, religious art, and photographs. Some of the country's foremost ethnographers and anthropologists are on the museum's staff. Nearly 1,000 pre-Columbian Costa Rican stone and ceramic objects dating from about AD 1000 are on display here. The artifacts were taken from the country in the late 19th century by businessman Minor Keith during the construction of the Atlantic Railroad and were repatriated from the Brooklyn Museum in 2012. Outside are a veranda and a pleasant, manicured courtyard garden. A former army headquarters, this now-tranquil building saw fierce fighting during a 1931 army mutiny and the 1948 revolution, as the bullet holes pocking its turrets attest. But it was also here that three-time president José Figueres abolished the country's military in 1949.
