Jade was once a big deal in Central America, and here is its temple
San José's most unusual museum?
For many, this is San José's most unusual — and even overall best — museum, operated by the National Insurance Institute at its headquarters on Calles 9 and 11/Avenidas 7 and 9 (a building with impressive views out over the city from the top floor, by the way). Established in 1977 and renovated in 2003, it displays the world's most extensive collection of jade from the Americas - hundreds of archaeological, artistic, ethnographic, and even numismatic artifacts. There are also various rooms devoted to temporary exhibitions relating to history, science, and technology.
