History of World Expositions
Since 1851, when the first Universal Exposition took place in London, those events have sought to open a window for the countries to show its best progresses in terms of science, technology and architecture. Since then, every universal exposition has tried to leave a material –or immaterial- imprint that would last in time and would lay the foundations to transform the planet. 34 events of this nature have taken place, if we count the 2015 edition, which will be hosted in Milano.
