The Cisneros Collection, which comprises works of art ranging from European modern art to ethnographic objects produced in the Orinoco region, specializes in Latin American modern and contemporary art. The site is interesting because, although its classifications are evidently curatorial, hierarchychal, and sometimes a little bit obscure, the educational intent is skillfully interwoven into the unorthodox structure of the site. Also, there are some traditional and straightforward scroll-bars in order to search for artists or works, but also unexpected links that relate works, movements, and chronology.
Another plus: it is available in English, Spanish, and Portuguese
