Apart from the esthetic value of a museum that is, its relationship to the visiting public through the exhibited items, this has a scientific, real value represented by its cultural heritage.
The scientific heritage of the Natural Sciences Section comprises all the Collections gathered during the years, from its foundation up to present. Therefore, now, the Natural Sciences Section possesses the following heritage Collections, numbering over 20,000 items:
The richest collections are the botany, the gastropods and the insects. Apart from the indigenous collections, gastropod and insect collections contain numerous exotic exemplaries from the tropical and equatorial zones of the earth that are both scientifically and esthetically valuable. The other collections, although not so rich in items, enhance the scientific information of the heritage belonging to this Section through their special tri-dimensional display (corals, fishes, birds and mammals).
