Georges-Eugène Haussmann, commonly known as Baron Haussmann, was a French official who served as prefect of Seine (1853–1870), chosen by Emperor Napoleon III to carry out a massive urban renewal programme of new boulevards, parks and public works in Paris commonly referred to as Haussmann's renovation of Paris.

The Axe historique refers to a straightly aligned series of thoroughfare streets, squares, monuments and buildings that extend from the centre of Paris, France, to the west-northwest of the city. It is also known as the Voie Triomphale.

The Place de la Concorde is a public square in Paris, France. Measuring 7.6 ha in area, it is the largest square in the French capital. It is located in the city's eighth arrondissement, at the eastern end of the Champs-Élysées.

The Tuileries Garden is a public garden between the Louvre and the Place de la Concorde in the 1st arrondissement of Paris, France. Created by Catherine de' Medici as the garden of the Tuileries Palace in 1564, it was opened to the public in 1667 and became a public park after the French Revolution. Since the 19th century, it has been a place for Parisians to celebrate, meet, stroll and relax. During the 2024 Summer Olympics and Paralympics, it was the site of the Olympic and Paralympic cauldron.

The oldest traces of human occupation in Paris are human bones and evidence of an encampment of hunter-gatherers dating from about 8000 BC, during the Mesolithic period.

The Tuileries Palace was a royal and imperial palace in Paris which stood on the right bank of the Seine, directly in front of the Louvre Palace. It was the Parisian residence of most French monarchs, from Henry IV to Napoleon III, until it was burned by the Paris Commune in 1871.

The Palais-Royal is a former French royal palace located on Rue Saint-Honoré in the 1st arrondissement of Paris. The screened entrance court faces the Place du Palais-Royal, opposite the Louvre. Originally called the Palais-Cardinal, it was built for Cardinal Richelieu from about 1633 to 1639 by architect Jacques Lemercier. Richelieu bequeathed it to Louis XIII, before Louis XIV gave it to his younger brother, Philippe I, Duke of Orléans. As the succeeding Dukes of Orléans made such extensive alterations over the years, almost nothing remains of Lemercier's original design.

The Avenue de l'Opéra was created from 1864 to 1879 as part of Haussmann's renovation of Paris. It is situated in the center of the city, running northwest from the Louvre to the Palais Garnier, the primary opera house of Paris.

The Musée Carnavalet in Paris is dedicated to the history of the city. The museum occupies two neighboring mansions: the Hôtel Carnavalet and the former Hôtel Le Peletier de Saint Fargeau. On the advice of Baron Haussmann, the civil servant who transformed Paris in the latter half of the 19th century, the Hôtel Carnavalet was purchased by the Municipal Council of Paris in 1866; it was opened to the public in 1880. By the latter part of the 20th century, the museum was full to capacity. The Hôtel Le Peletier de Saint Fargeau was annexed to the Carnavalet and opened to the public in 1989.

Louis Tullius Joachim Visconti was an Italian-born French architect and designer.

Haussmann's renovation of Paris was a vast public works programme commissioned by French Emperor Napoleon III and directed by his prefect of the Seine, Georges-Eugène Haussmann, between 1853 and 1870. It included the demolition of medieval neighbourhoods that were deemed overcrowded and unhealthy by officials at the time, the building of wide avenues, new parks and squares, the annexation of the suburbs surrounding Paris, and the construction of new sewers, fountains and aqueducts. Haussmann's work was met with fierce opposition, and he was dismissed by Napoleon III in 1870. Work on his projects continued until 1927. The street plan and distinctive appearance of the centre of Paris today are largely the result of Haussmann's renovation.

The Louvre Palace, often referred to simply as the Louvre, is an iconic French palace located on the Right Bank of the Seine in Paris, occupying a vast expanse of land between the Tuileries Gardens and the church of Saint-Germain l'Auxerrois. Originally a defensive castle, it has served several government-related functions in the past, including intermittently as a royal residence between the 14th and 18th centuries. It is now mostly used by the Louvre Museum, which first opened there in 1793.

The Louvre Saint-Honoré building is a historic structure in Paris, occupying an entire urban block between the rue de Rivoli, the place du Palais-Royal, the rue Saint-Honoré, and the rue de Marengo, with a total floor surface of 47,000 square meters. It was originally erected in the early 1850s by the Pereire brothers who in 1855 opened an iconic hotel, the Grand Hôtel du Louvre, and an innovative street-level department store, branded from 1863 the Grands Magasins du Louvre. While the Grand Hôtel closed in 1887, the Grands Magasins expanded and kept operating in the building until 1974. From 1978 to 2016 they were succeeded by a specialized mall of antiques shops, the Louvre des Antiquaires, while the upper floors were repurposed as rented office space. Since 2020, the building's lower levels have been undergoing conversion to become the new flagship home of the Fondation Cartier pour l'Art Contemporain.

The city of Paris has notable examples of architecture from the Middle Ages to the 21st century. It was the birthplace of the Gothic style, and has important monuments of the French Renaissance, Classical revival, the Flamboyant style of the reign of Napoleon III, the Belle Époque, and the Art Nouveau style. The great Exposition Universelle (1889) and 1900 added Paris landmarks, including the Eiffel Tower and Grand Palais. In the 20th century, the Art Deco style of architecture first appeared in Paris, and Paris architects also influenced the postmodern architecture of the second half of the century.

Paris in the 17th century was the largest city in Europe, with a population of half a million, matched in size only by London. It was ruled in turn by three monarchs; Henry IV, Louis XIII, and Louis XIV, and saw the building of some of the city's most famous parks and monuments, including the Pont Neuf, the Palais Royal, the newly joined Louvre and Tuileries Palace, the Place des Vosges, and the Luxembourg Garden. It was also a flourishing center of French science and the arts; it saw the founding of the Paris Observatory, the French Academy of Sciences and the first botanical garden in Paris, which also became the first park in Paris open to the public. The first permanent theater opened, the Comédie-Française was founded, and the first French opera and French ballets had their premieres. Paris became the home of the new Royal Academy of Painting and Sculpture, and of some of France's most famous writers, including Pierre Corneille, Jean Racine, La Fontaine and Moliere. Urban innovations for the city included the first street lighting, the first public transport, the first building code, and the first new aqueduct since Roman times.

The following outline is provided as an overview of and topical guide to Paris:

The expansion of the Louvre under Napoleon III in the 1850s, known at the time and until the 1980s as the Nouveau Louvre or Louvre de Napoléon III, was an iconic project of the Second French Empire and a centerpiece of its ambitious transformation of Paris. Its design was initially produced by Louis Visconti and, after Visconti's death in late 1853, modified and executed by Hector-Martin Lefuel. It represented the completion of a centuries-long project, sometimes referred to as the grand dessein, to connect the old Louvre Palace around the Cour Carrée with the Tuileries Palace to the west. Following the Tuileries' arson at the end of the Paris Commune in 1871 and demolition a decade later, Napoleon III's nouveau Louvre became the eastern end of Paris's axe historique centered on the Champs-Élysées.

The Pavillon de Marsan or Marsan Pavilion was built in the 1660s as the northern end of the Tuileries Palace in Paris, and reconstructed in the 1870s after the Tuileries burned down at the end of the Paris Commune. Following the completion of the joining of the Louvre and the Tuileries in the 1850s and the demolition of the Tuileries' remains in the early 1880s, it is now the northwestern tip of the Louvre Palace. Since 1897 it has been part of the Musée des Arts Décoratifs, a separate institution from the Louvre.

The Hôtel du Louvre is a Parisian luxury hotel in the Second Empire style, with a 5-star rating. It is located opposite the Louvre Museum, on Place André-Malraux in the 1st arrondissement. It is owned by the Constellation Hotels Holdings group and operated by the Hyatt chain.
