The Louvre Pyramid (Pyramide du Louvre) is a large glass and metal pyramid, surrounded by three smaller pyramids, in the main courtyard (Cour Napoléon) of the Louvre Palace (Palais du Louvre) in Paris. The large pyramid serves as the main entrance to the Louvre Museum. Completed in 1989, it has become a landmark of the city of Paris.
Commissioned by the President of France François Mitterrand in 1984, it was designed by the architect I. M. Pei, who is responsible for the design of the Miho Museum in Japan, the MasterCard Corporate Office Building in Purchase, New York, the Rock and Roll Hall of Fame Museum in Cleveland, Place Ville Marie in Montreal, and the National Gallery of Art (East Building) in Washington, D.C. among others. The structure, which was constructed entirely with glass segments, reaches a height of 21.6 metres (about 71 feet); its square base has sides of 35 metres (115 ft). It consists of 603 rhombus-shaped and 70 triangular glass segments.
Wikipedia: Arc du Triomphe du Carrousel
The Arc de Triomphe du Carrousel (pronounced: [aʁk də tʁijɔ̃f dy kaʁusɛl]) is a triumphal arch in Paris, located in the Place du Carrousel. It was built between 1806 and 1808 to commemorate Napoleon’s military victories of the previous year. The more famous Arc de Triomphe de l’Étoile, across from the Champs Élysées, was designed in the same year; it is about twice the size and was not completed until 1836.
Designed by Charles Percier and Pierre François Léonard Fontaine, the arch was built between 1806 and 1808 by the Emperor Napoleon I, on the model of the Arch of Constantine (312 AD) in Rome, as a gateway of the Tuileries Palace, the Imperial residence. The destruction of the Tuileries Palace during the Paris Commune in 1871, allowed an unobstructed view west towards the more famous Arc de Triomphe.
It was originally surmounted by the famous horses of Saint Mark’s Cathedral in Venice, which had been captured in 1798 by Napoleon. In 1815, following the Battle of Waterloo and the Bourbon restoration, France ceded the quadriga to the Austrian empire which had annexed Venice under the terms of the Congress of Vienna. The Austrians immediately returned the statuary to Venice. The horses of Saint Mark were replaced in 1828 by a quadriga sculpted by Baron François Joseph Bosio, depicting Peace riding in a triumphal chariot led by gilded Victories on both sides. The composition commemorates the Restoration of the Bourbons following Napoleon’s downfall.
The Arc du Carrousel inspired the design of Marble Arch, constructed in London between 1826 and 1833.
