Enjoy a different museum

The Mef is a Scientific Research Center of great importance in our country, with a permanent staff of researchers and CONICET scholars, university students and collaborators.

In addition, it is a tourist and recreational attraction that offers a Permanent Exhibitions, programs and activities for adults and children, all year round. It provides jobs not only to a large permanent team, but also to temporary staff, independent professionals and suppliers.

Since March 13, our museum has been closed to the public, responding to health regulations imposed in the framework of control of the spread of Covid-19.

Since then, the Mef team has turned to work with the community through online resources, developing products for the whole family: games, activities, courses and our membership program: MemberMef.
