The second exposition held in Paris took place in a colossal elliptical building known as the Palais Omnibus. Designed by Léopold Hardy and Jean-Baptiste Sébastien Krantz, the building covered more than 15 hectares.

​

Inside of the Palais Omnibus, participating countries constructed pavilions in local architectural styles, setting the stage for the future of world expos as a global showcase of architectural pageantry.
