In the center of the Plaza was erected the Monumento a los Sitios by Agustí Querol Subirats, a Catalan sculptor who executed it in a modernist style; it still can be seen today.
The majority of the buildings were modernist and of a temporary nature, constructed with inexpensive materials such as wood, plaster and adobe, and torn down after the Exposition.
Among the exhibitors were both public institutions such as the French government and the Ministry of Development, and private businesses such as Altos Hornos de Vizcaya, which had its own pavilion.
Catalonia also had a significant presence (there was a small incident during a toast to the regional architect Josep Puig i Cadafalch that did not please some conservative Zaragozans).
The exposition coincided with several other congresses, which included the Science, National Agriculture, Chamber of Commerce, Exports, Economic and Tourism Society.
