World's fair


A world's fair, also known as a universal exhibition, is a large global exhibition designed to showcase the achievements of nations. These exhibitions vary in character and are held in different parts of the world at a specific site for a period of time, typically between three and six months.
The term "world's fair" is commonly used in the United States, while the French term, Exposition universelle is used in most of Europe and Asia; other terms include World Expo or Specialised Expo, with the word expo used for various types of exhibitions since at least 1958.
Since the adoption of the 1928 Convention Relating to International Exhibitions, the Paris-based Bureau International des Expositions has served as an international sanctioning body for international exhibitions; four types of international exhibition are organised under its auspices: World Expos, Specialised Expos, Horticultural Expos, and the Milan Triennial.
Osaka, Japan held the most recent World Expo in 2025, while Astana, Kazakhstan held the most recent Specialised Expo in 2017, and Doha, Qatar held the most recent Horticultural Expo in 2023.

History

In 1791, Prague organized the first World's Fair in Bohemia. The first industrial exhibition was on the occasion of the coronation of Leopold II as king of Bohemia. The exhibition was held in the Clementinum, and celebrated the considerable sophistication of manufacturing methods in the region during that time period.
France had a tradition of national exhibitions, which culminated with the French Industrial Exposition of 1844 held in Paris. This fair was followed by other national exhibitions in Europe. In 1851, the "Great Exhibition of the Works of Industry of All Nations" was held in the Crystal Palace in Hyde Park, London, United Kingdom. It was an idea of Prince Albert, Queen Victoria's husband.
The character of world fairs, or expositions, has evolved since. Three eras can be distinguished: the era of industrialization, the era of cultural exchange, and the era of nation branding.

Industrialization (1851–1938)

The first era, the era of "industrialization", roughly covered the years from 1850 to 1938. In these years, world expositions were largely focused on trade and displayed technological advances and inventions. World expositions were platforms for state-of-the-art science and technology from around the world. The world expositions of 1851 London, 1853 New York, 1862 London, 1876 Philadelphia, Paris 1878, 1888 Barcelona, 1889 Paris, 1891 Prague, 1893 Chicago, 1897 Brussels, 1900 Paris, 1904 St. Louis, 1915 San Francisco, and 1933–1934 Chicago were notable in this respect. Inventions such as the telephone were first presented during this era. This era set the basic character of the world fair.

Cultural exchange (1939–1987)

The 1939–1940 New York World's Fair, and those that followed, took a different approach, one less focused on technology and aimed more at cultural themes and social progress. For instance, the theme of the 1939 fair was "Building the World of Tomorrow"; at the 1964–1965 New York World's Fair, it was "Peace Through Understanding"; at the 1967 International and Universal Exposition in Montreal, it was "Man and His World". These fairs encouraged effective intercultural communication along with sharing of technological innovation.
The 1967 International and Universal Exposition in Montreal was promoted under the name Expo 67. Event organizers retired the term world's fair in favor of Expo, a term already popular in French language and used as far back as the Brussels World Fair in 1958. The Montreal Expos, a former Major League Baseball team, was named for the 1967 fair.

Nation branding (1988–present)

From World Expo 88 in Brisbane onwards, countries started to use expositions as a platform to improve their national image through their pavilions. Finland, Japan, Canada, France, and Spain are cases in point. A major study by Tjaco Walvis called "Expo 2000 Hanover in Numbers" showed that improving national image was the main goal for 73% of the countries participating in Expo 2000. Pavilions became a kind of advertising campaign, and the Expo served as a vehicle for "nation branding". According to branding expert Wally Olins, Spain used Expo '92 and the 1992 Summer Olympics in Barcelona in the same year to underscore its new position as a modern and democratic country and to show itself as a prominent member of the European Union and the global community.
At Expo 2000 Hanover, countries created their own architectural pavilions, investing, on average, €12 million each. Given these costs, governments are sometimes hesitant to participate, because the benefits may not justify the costs. However, while the effects are difficult to measure, an independent study for the Dutch pavilion at Expo 2000 estimated that the pavilion generated around €350 million of potential revenues for the Dutch economy. It also identified several key success factors for world-exposition pavilions in general.

Types

At present there are two types of international exhibition: World Expos and Specialised Expos. World Expos, previously known as universal expositions, are the biggest category events. At World Expos, participants generally build their own pavilions. They are therefore the most extravagant and most expensive expos. Their duration may be between six weeks and six months. Since 1995, the interval between two World Expos has been at least five years. World Expo 2015 was held in Milan, Italy, from 1 May to 31 October 2015.
Specialised Expos are smaller in scope and investments and generally shorter in duration; between three weeks and three months. Previously, these Expos were called Special Exhibitions or International Specialized Exhibitions but these terms are no longer used officially. Their total surface area must not exceed and organizers must build pavilions for the participating states, free of rent, charges, taxes and expenses. The largest country pavilions may not exceed 1,000 m2. Only one Specialised Expo can be held between two World Expos.
An additional two types of international exhibition may be recognized by the BIE: horticultural exhibitions, which are joint BIE and AIPH-sanctioned 'garden' fairs in which participants present gardens and garden pavilions; and the semi-regular Milan Triennial art and design exhibition, held in Milan, Italy, with the BIE granting official international exhibition status to 14 editions of the Triennale between 1996 and 2016.

World Expos

World Expos encompass universal themes that affect the full gamut of human experience, and international and corporate participants are required to adhere to the theme in their representations. Registered expositions are held every 5 years because they are more expensive as they require total design of pavilion buildings from the ground up. As a result, nations compete for the most outstanding or memorable structure—for example Japan, France, Morocco, and Spain at Expo '92. Sometimes prefabricated structures are used to minimize costs for developing countries, or for countries from a geographical block to share space.
In the 21st century the BIE has moved to sanction World Expos every five years; following the numerous expos of the 1980s and 1990s, some see this as a means to cut down potential expenditure by participating nations. The move was also seen by some as an attempt to avoid conflicting with the Summer Olympics. World Expos are restricted to every five years, with Specialized Expos in the in-between years.

Specialised Expos

Specialized Expos are usually united by a precise theme—such as "Future Energy", "The Living Ocean and Coast", or "Leisure in the Age of Technology". Such themes are more specific than the wider scope of world expositions.
Specialized Expos are usually smaller in scale and cheaper to run for the host committee and participants because the architectural fees are lower and they only have to customize pavilion space provided free of charge from the Organiser, usually with the prefabricated structure already completed. Countries then have the option of "adding" their own colours, design etc. to the outside of the prefabricated structure and filling in the inside with their own content.

Horticultural Expos

Horticultural Expos are co-regulated by International Association of Horticultural Producers. Like Specialised Expos are organized in a precise theme—such as "Green Desert, Better Environment", "Growing Green Cities", or "Building a Beautiful Home Featuring Harmonious Coexistence between Man and Nature".
The purpose of these exhibitions is to foster cooperation and the sharing of knowledge and solutions between countries, horticultural producers and agricultural industries by addressing the paramount issues of healthy lifestyles, green economies, sustainable living, education and innovation.

Legacies

Remaining structures

Most of the structures are temporary and are dismantled after the fair closes, except for landmark towers. By far the most famous of these is the Eiffel Tower, built for the Exposition Universelle. Although it is now the most recognized symbol of its host city Paris, there were contemporary critics opposed to its construction, and demands for it to be dismantled after the fair's conclusion.
Other structures that remain from these fairs:
  • 1851 – London: The Crystal Palace, from the first World's Fair in London, designed so that it could be recycled to recoup losses, was such a success that it was moved and intended to be permanent, only to be destroyed by a fire in 1936.
  • 1876 – Philadelphia: The Centennial Exposition's main building, Memorial Hall, is still in Fairmount Park, Philadelphia, and serving as the new home for the Please Touch Museum. The space under the entrance to Memorial Hall houses a scale model of the entire Exposition.
  • 1880 – Melbourne: The World Heritage–listed Royal Exhibition Building in Melbourne, constructed for the Melbourne International Exhibition.
  • 1893 – Chicago: The Museum of Science and Industry in Chicago is housed in the former Palace of Fine Arts, one of the last remaining buildings of the World's Columbian Exposition. In conjunction with the fair, the Art Institute of Chicago building was built to house conferences, as the World's Congress Auxiliary Building. The Garden of the Phoenix, a remnant of the Japanese pavilion, also survives. The intent or hope was to make all Columbian structures permanent, but most of the structures burned, possibly the result of arson during the Pullman Strike. The foundation of the world's first Ferris wheel, which operated at the Exposition, was unearthed on the Chicago Midway during a construction project by the University of Chicago, whose campus now surrounds the Midway. Relocated survivors include the Norway pavilion, a small house now at a museum in Wisconsin, and the Maine State Building, now at the Poland Springs Resort in Maine.
  • 1894 – San Francisco: The Japanese Tea Garden in San Francisco's Golden Gate Park is the last major remnant of the California Midwinter International Exposition. Large ornamental wooden gates and a pagoda from the 1915 Panama–Pacific International Exposition were brought in after the latter fair closed, making the Tea Garden a rare if not unique instance of a survivor that incorporates architectural features from two completely separate fairs.
  • 1897 – Nashville: A full-scale replica of the Parthenon was built for the Tennessee Centennial and International Exposition where it stands today in Nashville's Centennial Park. It features plaster reproductions of the Elgin Marbles and, in 1990, a re-creation of the original Athena Parthenos statue was installed inside just as it was in the original Parthenon in ancient Greece.
  • 1900 – Paris: the Grand Palais and Petit Palais.
  • File:1904 World's Fair Administration Building seen from the southeast with the Italian Pavilion in the foreground.jpg|thumb|Brookings Hall at Washington University in St. Louis, the administration building of the 1904 World's Fair1904 – St. Louis: The St. Louis Art Museum in Forest Park, originally the Palace of the Fine Arts, and Brookings Hall at Washington University in St. Louis, are remnants of the Louisiana Purchase Exposition, better known as the St. Louis World's Fair. The aviary in Forest Park gave root to the St. Louis Zoo.
  • 1906 – Milan: The Civic Aquarium of Milan built for the Milan Exposition is still open after 100 years and was recently renovated. The International Commission on Occupational Health was settled in Milan during the fair and had its first congress in the Expo pavilions. In June 2006 the ICOH celebrated the first century of its life in Milan. An elevated railway with trains running at short intervals linked the fair to the city center. It was dismantled in the 1920s.
  • 1909 – Seattle: The landscaping from the Alaska–Yukon–Pacific Exposition in Seattle still forms much of the University of Washington campus. The only major building left from the AYPE, Architecture Hall, is used by the university's architecture school.
  • 1915 – San Francisco: The Palace of Fine Arts in San Francisco and its adjacent artificial lagoon are the only major remnants of the Panama–Pacific International Exposition still in their original locations on the former fairgrounds, but the building is almost entirely a reconstruction. The plaster-surfaced original, not intended to survive after the fair, was a crumbling ruin in 1964 when all but the steel framework was demolished so that it could be reproduced in concrete. The San Francisco Civic Auditorium, now the Bill Graham Civic Auditorium, is another major legacy of the fair but was built off-site in the city's Civic Center. The independent Panama–California Exposition in San Diego left a substantial legacy of permanent buildings and other structures which today define its site, San Diego's central Balboa Park, including the Prado walkway, the California Tower and Dome, the 1,500-foot Cabrillo Bridge, the lily pond and botanical gardens, and the Spreckels Organ Pavilion.
  • 1929 – Seville and Barcelona: much survives from the two simultaneous fairs Spain hosted that year. The most famous are the remnants of the Ibero-American Exposition in Seville, in which the Spanish Pavilion's Plaza de España forms part of a large park and forecourt. Most of that fair's pavilions have survived and been adapted for other uses, with many of them becoming consulates-general for the countries that built them. The Barcelona International Exposition featured the famous German pavilion designed by Mies van der Rohe, which was demolished but later rebuilt on the original site.
  • 1936 – Johannesburg: The Empire Exhibition, South Africa was built close to the University of the Witwatersrand, and by the late 1970s the growth of the university was large enough to incorporate the permanent buildings from the exhibition. In 1985, the university purchased the South African Government Building; the two Heavy Machinery Halls, now called Empire Hall and the Dining Hall; the Hall of Transport; the Tower of Light; the Cape Dutch complex; and the Bien Donne Restaurant.
  • 1939 – New York City: The New York City Building from the 1939's World Fair, was reused for the 1964 World's Fair and is now the Queens Museum. Parachute jump was a ride from the fair. It was moved to the Coney island boardwalk in Brooklyn.
  • 1942 – Rome: A special case is the EUR quarter in Rome, built for a World's Fair planned for 1942 but cancelled because of World War II. Today it hosts governmental and private offices, and several museums.
  • 1958 – Brussels: In Brussels, the Atomium still stands at the exposition site. It is a 165-billion-times-enlarged iron-crystal-shaped building. Until June 2012, the "American Theatre" on the Expo grounds was frequently used as a television studio by the VRT.
  • 1962 – Seattle: The Space Needle theme building of the Century 21 Exposition commonly known as the Seattle World's Fair still stands as a Seattle icon and landmark. The Seattle Center Monorail, the other widely known futuristic feature of the fair, still operates daily. The US pavilion became the Pacific Science Center. The original exterior and roof of the Washington State Pavilion has been preserved as a landmark, and now is part of Climate Pledge Arena.
  • 1964 – New York City: many structures still stand
  • * The Unisphere, built for the second New York World's Fair, stands on its original site in Flushing Meadows, Queens
  • * New York Hall of Science, built for the fair, continues to operate as a science museum, similar to its original role
  • * The Port Authority Heliport and Exhibit is now the Terrace on the Park event and catering venue
  • * The New York State Pavilion is mostly derelict, but is still an icon, with its observation towers prominently featured in 1997's Men in Black. The Theaterama building is the only portion still maintained, and is used by the Queens Theater. The Tent of Tomorrow building and observation towers are being restored as of 2019.
  • * The New York City Pavilion, a holdover form the 1939 fair, continues to serve as the home of the Queens Museum
  • * Other artifacts remain throughout the park, and many buildings were transported for use elsewhere and continue to function.
  • 1967 – Montreal: Among the structures still standing from Expo 67 in Montreal are Moshe Safdie's Habitat 67, Buckminster Fuller's American pavilion the "Montreal Biosphere", the Jamaica Pavilion, the Tunisia Pavilion, and the French pavilion.
  • 1968 – San Antonio: San Antonio kept the Tower of the Americas, the Institute of Texan Cultures and the Convention Center from HemisFair '68.
  • 1970 – Osaka: The Tower of the Sun was left standing, but was neglected after the conclusion of the Expo '70. After restoration to the structure was completed, the museum inside the tower was re-opened on 18 March 2018.
  • 1974 – Spokane: Spokane still has its Riverfront Park that was created for Expo '74—the park remains a popular and iconic part of Spokane's downtown.
  • 1982 – Knoxville: The Sunsphere from the Knoxville World's Fair remains as a feature of Knoxville's skyline.
  • 1984 – New Orleans: The main pavilions of the 1984 New Orleans World's Fair became the Ernest N. Morial Convention Center, which is also known for its use as a shelter of last resort during Hurricane Katrina and later hosted the Miss Universe in 2022.
  • 1986 – Vancouver: In Vancouver, many Expo 86 projects were designed as legacy projects. Of note are the Skytrain, Science World and Canada Place.
  • 1988 – Brisbane: The Skyneedle, the symbol tower of Expo '88 in Brisbane, Queensland, Australia, still stands. Other survivors are the Nepalese Peace Pagoda of the Nepalese representation, now at the transformed World Expo '88 site South Bank Parklands, and the Japan Pond and Garden from the Japanese representation, now at the Brisbane Mount Cooth-tha Botanic Gardens. In 2018 the World Expo 88 Art Trail was re-birthed and dramatically expanded as part of the 30th Anniversary of World expo 88, now forming a Major tourist attraction in its own right.
  • 1992 – Seville: The pavilions of Expo '92 in Seville had been converted into a technological square and a theme park.
  • 1998 – Lisbon: The main buildings of Expo '98 in Lisbon were completely integrated into the city itself and many of the art exhibition pieces still remain.
  • 2005 – Nagoya: The home of Satsuki & Mei Kusakabe, built for the 2005 Expo in Aichi, remains operating at its original site in Morikoro Park and is a popular tourist attraction, eventually being incorporated into Ghibli Park in 2022.
