One of the most important places of science in Barcelona is El Parc de la Ciutadella. It holds the Zoology museum, the Green House (Hivernacle), the Shade House (Umbracle), the Zoo, one artificial lake with little boats, the reproduction of one Mammuth and this fountain where the students are. It was an ideal location to discuss about the role of the social and natural sciences in the life of the medicine doctor and to imagine the place of the Universal Exhibition of 1888.
