About the museum
The Museo Argentino de Ciencias Naturales Bernardino Rivadavia (MACN) is Argentina’s oldest natural history museum. Located in Parque Centenario in Buenos Aires, it is known for its scientific collections, research, and educational work (MACN Official Website).
History
Proposals for the museum date to 1812, and it was officially established in 1826. Another account describes it as founded in 1823 through the vision of Bernardino Rivadavia (About Buenos Aires). Its early collections were housed in a former Dominican convent and included specimens of Argentina’s biodiversity and geology.
The museum faced political and logistical difficulties, including forced relocations and losses of resources during periods of instability. Renewed investment and leadership in the mid-19th century supported new collaborations and collection growth.
German naturalist Hermann Burmeister became director in 1862, following a recommendation by Alexander von Humboldt. He established the Argentine Paleontological Society and expanded the museum’s research in paleontology, zoology, botany, and anthropology.
The current building in Parque Centenario was completed in the early 20th century. Its eclectic architecture includes Gothic features such as pointed arches and owl sculptures. Under President Juan Perón, an annex was added for the National Natural Sciences Institute. Since 1996, the museum has been part of the National Research Council (CONICET); its online data bank was launched in 2002 (MACN Official Website).
What to see and learn
The museum has thirteen permanent exhibition halls and collections of more than 2 million specimens, making it a major repository of South American natural history.
- Paleontology Fossils of dinosaurs including Carnotaurus, Eoraptor, Herrerasaurus, and Patagosaurus, as well as Cenozoic mammals such as Glyptodon and Megatherium.
- Geology and meteorites Displays of Argentine minerals and meteorites.
- Antarctic research Specimens from Argentine Antarctic expeditions.
- Aquarium and zoological exhibits Live and preserved native and exotic species, including birds, mammals, reptiles, amphibians, and insects.
Other facilities include an auditorium, art gallery, library, and café.
MACN’s research in paleontology, zoology, and botany has contributed to the identification of numerous species and to scientific understanding. Exhibitions on endangered species and climate change address environmental responsibility.
The museum’s educational activities include school visits, workshops, lectures, and hands-on activities. Collaborations with local schools and universities support STEM education, curriculum development, inclusivity, and experiential learning (About Buenos Aires; buenosaires.com/education). Its programming also supports lifelong learning and scientific literacy (buenosaires.com/education).
The collections document Argentina’s natural heritage and highlight the country’s ecosystems, contributing to public understanding of conservation and Argentine identity (Turismo Buenos Aires). The museum is part of Buenos Aires’ network of museums and cultural centres and attracts local and international visitors, including during La Noche de los Museos (Turismo Buenos Aires).
As a historic institution, MACN supports community engagement, civic pride, and nearby businesses, and creates local employment opportunities.
