Remaining as enduring landmarks from the Exposition of 1900 are several major structures that continue to grace the Parisian landscape: the Grand Palais, the Petit Palais, the Pont Alexandre III, the Gare d’Orsay railroad station (now the Musée d’Orsay), and two original entrances of Paris Métro stations designed by Hector Guimard. These architectural marvels serve as tangible reminders of the grandeur and innovation showcased during this historic event.
The Exposition saw the participation of countries from around the globe, invited by France to exhibit their accomplishments and cultures. Of the fifty-six countries extended invitations, forty accepted, along with numerous colonies and protectorates of France, the Netherlands, Britain, and Portugal. Notable pavilions were erected by nations such as the United States, Germany, China, Siam, Japan, Mexico, Russia, and the South African Republic, each offering unique glimpses into their respective achievements and heritage.

Characterized by their temporary nature, the Exposition buildings were constructed using iron frames covered with plaster and staff, an inexpensive artificial stone. Despite some being unfinished at the event’s commencement, the majority of these structures were swiftly demolished following its conclusion. Among the most memorable pavilions were those devoted to technology and the sciences, such as the Palace of Optics, which featured attractions like the Great Paris Exposition Telescope. This telescope, the largest of its kind at the time, mesmerized visitors with its ability to enlarge the image of the moon ten thousand times, projected onto a vast screen within a hall accommodating two thousand spectators. Additionally, innovative cinematic experiences, like the Cinéorama, offered immersive journeys, captivating audiences with simulated balloon voyages projected on a massive circular screen by synchronized projectors.
