Eugenio Serrano de Casanova (journalist, writer and entrepreneur) tried to launch an exposition in 1886, and when that failed, the Mayor of Barcelona, Francesc Rius i Taulet, took over[1] the planning of the project.

[1] More than 2 million people from Spain, the rest of Europe, and other international points of embarkation visited the exhibition,[3] which made the equivalent of 1,737,000 United States dollars.

[2] The fair was opened by Alfonso XIII of Spain and Maria Christina of Austria.

[6] The main legacy of the 1888 World Fair is the Ciutadella Park: the World Fair served as the opportunity for Barcelona to rid itself of the hated citadel and transform it into a central park for the city's denizens.

The entire Ciutadella Park in its present layout is a product of the World Fair, with its monumental fountain and small ponds, its Castell dels tres dracs (Castle of the Three Dragons) built by Domènech i Montaner to house the World Fair's café / restaurant, which later served to house the Zoology Museum, Hivernacle (Glasshouse or Greenhouse), the classicist Geology Museum and the Umbracle (a remarkable shaded structure for plants).
