The Louvre Pyramid (Pyramide du Louvre) is a large glass and metal structure designed by the Chinese-American architect I. M. Pei. The pyramid is in the main courtyard (Cour Napoléon) of the Louvre Palace in Paris, surrounded by three smaller pyramids. The large pyramid serves as the main entrance to the Louvre Museum. Completed in 1988 as part of the broader Grand Louvre project, it has become a Paris landmark. (Source: Wikipedia)
The Arc de Triomphe du Carrousel is a triumphal arch in Paris, located in the Place du Carrousel. It is an example of Neoclassical architecture in the Corinthian order. It was built between 1806 and 1808 to commemorate Napoleon's military victories in the Wars of the Third and Fourth Coalitions. The Arc de Triomphe de l'Étoile, at the far end of the Champs Élysées, was designed in the same year; it is about twice the size and was not completed until 1836.
