Fundación Miguel Lillo (Miguel Lillo Foundation).
Address: the corner of San Lorenzo and Miguel Lillo streets.

Miguel Lillo Foundation is one of the most important natural science institutions in Argentina and South America.

It was founded by the eminent researcher and naturalist Miguel Lillo, who donated, in December, 1930, a whole block of land with his ancestral home, his library, his zoology and botany collection to the Tucumán National University, plus a sum of money on condition that it should be applied to the creation of a center for the research and study of natural science.

Today, surrounded by a stately park, there lies the Foundation headquarters, some of the buildings being modern and recent, as a symbol of the continuity and the development of Lillo's wishes.

Nearby the walls in ruins of the former home of the researcher, which are protected like relics, new premises house countless collections of mineralogy, zoology and botany.

In the Foundation there is an herbarium with 590,000 samples, as well as a very important zoology collection and others centered on geology and paleontology which are of no smaller significance.
