Alexander von Humboldt returns to visit the Old School of Mines, now turned into the Mining Palace of the School of Engineering of UNAM.

Homboldt had a close relationship with the School of Mining (now the School of Engineering of UNAM), because its founding director, Fausto de Elhuyar (1755-1833) and the scholar of Mineralogy, Andrés Manuel del Río (1764-1849), studied at the Mining Academy of Freiberg, just like him. Blueprints, drawings, and lines recreate the time when the explorer rediscovered the Americas in the exhibition: Humboldt at Mining Palace. First School of Sciences in the Americas, organized at 250 years of his birth.
