The origin of World Fair aka World Expo
The credit of first ever World Expo goes to Prince Albert, the spouse of Queen Victoria of the United Kingdom. He suggested the idea of a big exhibition in 1849. This was a historic moment for UK as well as the global community later on. The Great Exhibition of 1851 in London truly kicked off what we now know as the World’s Fairs. It was held in the Crystal Palace, and millions of visitors came to see the latest innovations of the time, which inspired new ideas in trade, tourism, and education. An interesting fact about this venue was that it was built in only 190 days for the exhibition.
This iconic event set the example for future Universal Exhibitions. These fairs have developed gradually. Some famous structures, like the Eiffel Tower from the 1889 Paris Fair and the Golden Bridge Gate from the 1939 World Expo, San Francisco, still stand today as symbols of progress.
World Fairs are organized every five years now. It is a matter of pride and excitement for the countries chosen as hosts of a World Expo, and they start Expo preparations years in advance before the Expo to host it meticulously. It is important to note that there is a certain criteria to be chosen for hosting Expo.
