凯旋门A triumphal arch is a structure in the shape of a monumental archway, usually built to celebrate a victory in war. The arch is invariably a free-standing structure, quite separate from city gates or walls. In its simplest form a triumphal arch consists of two pillars connected by an arch, crowned with a superstructure or attic on which a statue might be mounted or which bears commemorative inscriptions. More elaborate triumphal arches have flanking subsidiary archways, typically a pair.The rhythmic ABA motif— of central arched void flanked by smaller ones— was adapted in Classical architecture, particularly since the Renaissance, to articulate the walls of structures. The voids may take the form of niches or be "blind", with masonry continuous behind.凡尔赛宫The Château de Versailles, or simply Versailles, is a royal château in Versailles, France. In English it is often referred to as the Palace of Versailles. When the château was built, Versailles was a country village, but it is now a suburb of Paris with city status in its own right. From 1682, when King Louis XIV moved from Paris, until the royal family was forced to return to the capital in 1789, the Court of Versailles was the centre of power in Ancien Régime France.In 1660, Louis XIV, who was approaching majority and the assumption of full royal powers from the advisors who had governed France during his minority, was casting about for a site near Paris but away from the tumults and diseases of the crowded city. He had grown up in the disorders of the civil war between rival factions of aristocrats called the Fronde and wanted a site where he could organize and completely control a government of France by absolute personal rule. He settled on the royal hunting lodge at Versailles, and over the following decades had it expanded into the largest palace in Europe. Versailles is famous not only as a building, but as a symbol of the system of absolute monarchy which Louis XIV espoused.罗浮宫The Louvre Museum (French: Musée du Louvre) in Paris, France, is the largest, oldest, most important and famous art gallery and museum in the world. The Louvre has a long history of artistic and historic conservation, from the Capetian dynasty until today. The building was previously a royal palace, and is famous for holding several of the world's most prestigious works of art, such as Leonardo da Vinci's Mona Lisa, The Virgin and Child with St. Anne, Madonna of the Rocks and Alexandros of Antioch's Venus de Milo. Located in the center of the city of Paris, between the Rive Droite of the Seine and the rue de Rivoli in the Ier arrondissement, it is accessed by the Palais Royal - Musée du Louvre Metro station. The equestrian statue of Louis XIV constitutes the starting point of the axe historique, but the palace is not aligned on this axis.In 2005, the Louvre received a record 7.3 million visitors in part due to the success of Dan Brown's 2003 novel The Da Vinci Code[1]—a significant boost of 22% compared to previous figures, placing the Louvre as the most visited monument in Paris.[2]艾菲尔铁塔The Eiffel Tower (pronounced /'aifəl'taʊɚ/; French: La Tour Eiffel, pronounced /'tur,e'fel/) is an iron tower built on the Champ de Mars beside the River Seine in Paris. It is the tallest structure in Paris and possibly the most recognized symbol in the world[1]. Named after its designer, engineer Gustave Eiffel, it is the most visited monument in the world; 6,428,441 people visited the tower in 2005[2] and more than 200,000,000 since its construction [3]. Including the 20.75 m (70 ft) antenna, the structure is 320.75 m (1070 ft) high which is about 81 stories. In 1902, it was struck by lightning, which caused builders to reconstruct 300 feet of the top. The lights illuminating the tower also had to be replaced, due to short-circuiting.At the time of its construction in 1889, the tower replaced the Washington Monument as the world's tallest structure, a title it retained until 1930, when New York City's Chrysler Building (1063.33 ft tall) was completed[4]. The tower is now the fifth-highest structure in France[citation needed]. The Eiffel Tower is the highest structure in Paris, with the second-highest being the Tour Montparnasse.The structure of the Eiffel Tower weighs 7300 tons[5]. There are 1660 steps[6] (360 to the first level, another 359 to the second). It is not possible for the public to reach the summit via the stairs, lifts are required beyond the second platform. Lift tickets may be purchased at the base or either platform.Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 3.25 inches, due to thermal expansion of the metal on the side facing the sun [citation needed].Maintenance of the tower includes applying 50/60 tons of three graded tones of paint every seven years to protect it from rust. On occasion, the color of the paint is changed — the tower is currently painted a shade of brownish-gray. However, few people realize that the tower is actually painted three different colors in order to make it look the same color. The colors change from dark to light from top to bottom, but it looks the same because of the background (the sky being light and the ground being dark)[7]. On the first floor, there are interactive consoles hosting a poll for the color to use for a future session of painting. The co-architects of the Eiffel Tower are Emile Naugier, Maurice Koechlin and Stephen Sauvestre[8].圣母院Notre Dame de Paris (French for "Our Lady of Paris", meaning the church in Paris dedicated to the Virgin Mary), often known simply as Notre Dame in English, Gothic cathedral on the eastern half of the Île de la Cité in Paris, France, with its main entrance to the west. A major tourist destination, it is still used as a Roman Catholic cathedral and is the seat of the Archbishop of Paris. Notre Dame de Paris is widely considered one of the finest examples of French Gothic architecture.
