These temporary cities used a permanent-looking material that appeared amazingly like marble. It was called "staff" and consisted of plaster, hemp fibers, and a little cement.

Besides Hyde Park, two alternative locations suggested for the Great Exhibition were Leicester Square and Isle of Dogs. (The last one would have been kind of ironic, since dogs were not allowed into the expo grounds.)

Expo 2020 in Dubai then took this general idea and magnified it 100x, with mashrabiyas and windcatchers that showed how ancient architecture was more than a match for 21st-century climate change. Expo City Dubai

Their pavilion for Expo 2020 was a Mobius strip that ended in screams. No, really. You could choose to exit the the sly, twisty pavilion on a slide -that ended with shouts of joy from those who zoomed down it. Brilliant. Expo 2025 Osaka Kansai Luxembourg Expo Pavilion

This is going to be a hothouse orchid of a show.

When your pavilion is inspired by ribbon candy.

I love the echoes of the Boardwalk in the US pavilion 2015, and the UK's Seed Cathedral in 2010. For me, it slashes into the air the way Lucio Fontana's gashes in a canvas made his paintings impossible to look away from. #EXPO2025 #trahanarchitects

I want to see Luxembourg top its Expo 2020 pavilion -the gleaming white one that was based on a Mobius strip, and where you heard screams every time you walked by ... from people using the 2nd story slide to exit. #Expo2025 #Osaka2025 #Japan2025

If the US wins the 2031 International Horticultural Expo, it'll be boldly inventive. But in rooting around horticulture’s past, several ingenious outliers show up, like the young 1960s London couple who sold flowers from the back of a taxi. AIPH youtube.com/watch?v=QSpKRD…

The worst thing Expos have ever done? Human zoos. The last one, amazingly, was at Expo ’58 in Brussels -just 4 years after Brown v. Board of Education. Exhibit explores experiences of humans put on display at 1904 World’s Fair in St. Louis pbs.org/newshour/show/…

At the 1867 Paris Expo, fans mobbed the Steinway & Sons exhibit in a scene after the piano maker became the first American manufacturer to receive the Grand Gold Medal of Honor at the fair—standing out from what official accounts said were 158 companies exhibiting 338 pianos.

3. World’s fairs are often built around anniversaries of great events . For example, the 1889 Exposition Universelle in Paris honored the French revolution a century before, while the 1876 Centennial International Exhibition in Philadelphia paid homage to the American Revolution.

Paris’ 1867 Exposition Universelle celebrated the fine arts by exhibiting works of the then-well-known Jean-Louis-Ernest Meissonier and Jean-Léon Gérôme. But fair organizers also rejected the works of Édouard Manet, Claude Monet, Camille Pissarro, and Paul Cézanne.
