The Exposition Universelle of 1900 (French pronunciation: [ɛkspozisjɔ̃ ynivɛʁsɛl]), better known in English as the 1900 Paris Exposition, was a world's fair held in Paris, France, from 14 April to 12 November 1900, to celebrate the achievements of the past century and to accelerate development into the next. It was the sixth of ten major expositions held in the city between 1855 and 1937. It was held at the esplanade of Les Invalides, the Champ de Mars, the Trocadéro and at the banks of the Seine between them, with an additional section in the Bois de Vincennes, and it was visited by more than fifty million people. Many international congresses and other events were held within the framework of the exposition, including the 1900 Summer Olympics.

Many technological innovations were displayed at the fair, including the Grande Roue de Paris ferris wheel, the Rue de l'Avenir moving sidewalk, the first ever regular passenger trolleybus line, escalators, diesel engines, electric cars, dry cell batteries, electric fire engines, talking films, the telegraphone (the first magnetic audio recorder), the galalith and the matryoshka dolls. It also brought international attention to the Art Nouveau style. Additionally, it showcased France as a major colonial power through numerous pavilions built on the hill of the Trocadéro Palace.

Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, curved, or may consist of two or more straight pieces connected at angles.

Types of stairs include staircases (also called stairways) and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, ladders, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps).
