The National Museum of Natural Sciences is one of the most important scientific research institutes in the country in the field of natural sciences. The present National Museum of Natural Sciences was created by King Carlos III, in 1771, like Royal Cabinet of Natural History. With a staff of more than 70 researchers in areas ranging from paleobiology and geology to ecology and climate change through environmental biology and biodiversity, the Museum is one of the emblematic centers of the Consejo Superior de Investigaciones Científicas (CSIC). The challenge is to transmit the knowledge generated by our researchers to society. The Public Programs department plans, designs and implements the educational activities that the Museum offers the public with the objective of complementing its visit making it more dynamic and participatory. This program is also organized with the aim of bringing science to society, showing the work of researchers and collections collections of the Museum. The collections of the National Museum of Natural Sciences have their origin in the Royal Cabinet of Natural History, founded in 1771 by Carlos III. With more than 6 million specimens preserved in several collections, the Museum can be considered as one of the main reference centers for fauna, not only Spanish, but also circummediterránea, not forgetting the negligible representation of fauna of other biogeographic regions accumulated in its collections. Collections as a result of scientific expeditions made by our naturalists during the eighteenth and nineteenth centuries. In addition to these historical collections, the Museum's collections contain more recent collection material, obtained as a result of the successive researches developed in the institution. In these collections, which are the subject of an obligatory consultation in a multitude of subjects, the so-called "types" that are the ones that have served to describe new species stand out for their importance. In addition to the conservation and extension of these collections, research projects of various kinds are also carried out: documentation of historical collections, conservation and management techniques, taxonomic studies, etc. The activities of the Museum are open to the sponsorship of all those companies and entities interested in collaborating in the diffusion of our natural heritage and of the culture and scientific research. Some of the collaborators to the various activities of the museum are Azuvi, Eroski, Matador, IBM, Philips, Roche, elsports etc.
