World’s Fairs are global events that celebrate great human achievements in engineering, culture and innovation. For example, the 1889 Exposition Universelle in Paris saw the construction of the Eiffel Tower, a feat of engineering designed to commemorate the centenary of the French Revolution on the occasion of this exhibition. Almost 140 years later, Riyadh, the capital of Saudi Arabia, a country with towering ambitions, has been chosen to host Expo 2030. This choice was determined by a secret ballot in which Riyadh received 119 votes out of 165.
