Notre-Dame de Paris in the context of "Spire of Notre-Dame de Paris"

Beauty is commonly described as a feature of objects that makes them pleasurable to perceive. Such objects include landscapes, sunsets, humans and works of art. Beauty, art and taste are the main subjects of aesthetics, one of the fields of study within philosophy. As a positive aesthetic value, it is contrasted with ugliness as its negative counterpart.

One difficulty in understanding beauty is that it has both objective and subjective aspects: it is seen as a property of things but also as depending on the emotional response of observers. Because of its subjective side, beauty is said to be "in the eye of the beholder". It has been argued that the ability on the side of the subject needed to perceive and judge beauty, sometimes referred to as the "sense of taste", can be trained and that the verdicts of experts coincide in the long run. This suggests the standards of validity of judgments of beauty are intersubjective, i.e. dependent on a group of judges, rather than fully subjective or objective.

The Palais Garnier (French: [palɛ ɡaʁnje] , Garnier Palace), also known as Opéra Garnier (French: [ɔpeʁa ɡaʁnje] , Garnier Opera), is a historic 1,979-seat opera house at the Place de l'Opéra in the 9th arrondissement of Paris, France. It was built for the Paris Opera from 1861 to 1875 at the behest of Emperor Napoleon III. Initially referred to as le nouvel Opéra de Paris (the new Paris Opera), it soon became known as the Palais Garnier, "in acknowledgment of its extraordinary opulence" and the architect Charles Garnier's plans and designs, which are representative of the Napoleon III style. It was the primary theatre of the Paris Opera and its associated Paris Opera Ballet until 1989, when a new opera house, the Opéra Bastille, opened at the Place de la Bastille. The company now uses the Palais Garnier mainly for ballet. The theatre has been a monument historique of France since 1923.

The Palais Garnier has been called "probably the most famous opera house in the world, a symbol of Paris like Notre Dame Cathedral, the Louvre, or the Sacré Coeur Basilica". This is at least partly due to its use as the setting for Gaston Leroux's 1910 novel The Phantom of the Opera and, especially, the novel's subsequent adaptations in films and the popular 1986 musical. Another contributing factor is that among the buildings constructed in Paris during the Second Empire, besides being the most expensive, it has been described as the only one that is "unquestionably a masterpiece of the first rank".

Cathedrals, collegiate churches, and monastic churches like those of abbeys and priories, often have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church rarely has. Such churches are generally among the finest buildings locally and a source of regional pride. Many are among the world's most renowned works of architecture. These include St Peter's Basilica, Notre-Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Antwerp Cathedral, Prague Cathedral, Lincoln Cathedral, the Basilica of Saint-Denis, Santa Maria Maggiore, the Basilica of San Vitale, St Mark's Basilica, Westminster Abbey, Saint Basil's Cathedral, Antoni Gaudí's incomplete Sagrada Família and the ancient cathedral of Hagia Sophia in Istanbul, now a mosque.

The earliest large churches date from Late Antiquity. As Christianity and the construction of churches spread across the world, their manner of building was dependent upon local materials and local techniques. Different styles of architecture developed and their fashion spread, carried by the establishment of monastic orders, by the posting of bishops from one region to another and by the travelling of master stonemasons who served as architects. The successive styles of the great church buildings of Europe are known as Early Christian, Byzantine, Romanesque, Gothic, Renaissance, Baroque, Rococo, Neoclassical, and various Revival styles of the late 18th to early 20th centuries, and then Modern. Underlying each of the academic styles are the regional characteristics. Some of these characteristics are so typical of a particular country or region that they appear, regardless of style, in the architecture of churches designed many centuries apart.

A self-proclaimed monarchy is established when a person claims a monarchy without any historical ties to a previous dynasty. In many cases, this would make them a pretender to the throne (when a ruling dynasty is already established). The self-proclaimed monarch may be of an established state, such as Zog I of Albania, or of a micronation, such as Leonard Casley of Hutt River, Western Australia.

Eugène Emmanuel Viollet-le-Duc (French: [øʒɛn vjɔlɛ lə dyk]; 27 January 1814 – 17 September 1879) was a French architect and author, famous for his restoration of the most prominent medieval landmarks in France. His major restoration projects included Notre-Dame de Paris, the Basilica of Saint Denis, Mont Saint-Michel, Sainte-Chapelle, the medieval walls of the city of Carcassonne, and Château de Roquetaillade in the Bordeaux region.

His writings on decoration and on the relationship between form and function in architecture had a fundamental influence on a whole new generation of architects, including all the major Art Nouveau artists: Antoni Gaudí, Victor Horta, Hector Guimard, Henry van de Velde, Henri Sauvage and the École de Nancy, Paul Hankar, Otto Wagner, Eugène Grasset, Émile Gallé, and Hendrik Petrus Berlage. He also influenced the first modern architects, Frank Lloyd Wright, Mies van der Rohe, Auguste Perret, Louis Sullivan, and Le Corbusier, who considered Viollet-le-Duc as the father of modern architecture. English architect William Burges claimed that "We all cribbed on Viollet-le-Duc even though no one could read French".

Napoleon was crowned Emperor of the French on December 2, 1804 (11 Frimaire, Year XIII according to the French Republican calendar, commonly used at the time in France), at Notre-Dame de Paris in Paris. It marked "the instantiation of [the] modern empire" and was a "transparently masterminded piece of modern propaganda".Napoleon wanted to establish the legitimacy of his imperial reign with its new dynasty and nobility. To this end, he designed a new coronation ceremony unlike that for the kings of France, which had emphasised the king's consecration (sacre) and anointment and was conferred by the archbishop of Reims in Reims Cathedral. Napoleon's was a sacred ceremony held in the great cathedral of Notre Dame de Paris in the presence of Pope Pius VII. Napoleon brought together various rites and customs, incorporating ceremonies of Carolingian tradition, the ancien régime, and the French Revolution, all presented in sumptuous luxury.

On May 18, 1804, the Sénat conservateur vested the Republican government of the French First Republic in an emperor, and preparations for the coronation followed. Napoleon's elevation to emperor was overwhelmingly approved by the French people in the French constitutional referendum of 1804. Among Napoleon's motivations for being crowned were to gain prestige in international royalist and Roman Catholic circles and to lay the foundation for a future dynasty.

On 15 April 2019, at 18:18 CEST, a structural fire broke out in the roof space of Notre-Dame de Paris, a medieval Catholic cathedral in Paris, France, that is part of the "Paris, Banks of the Seine" UNESCO World Heritage Site.

The fire, which investigators believe was started by a cigarette or an electrical short circuit, destroyed the cathedral's wooden spire (flèche) and most of the wooden roof and severely damaged the cathedral's upper walls. The vaulted stone ceiling largely contained the burning roof as it collapsed, preventing extensive damage to the interior. Many works of art and religious relics were moved to safety, but others suffered smoke damage, and some of the exterior art was damaged or destroyed. The cathedral's altar, two pipe organs, and three 13th-century rose windows suffered little or no damage. Three emergency workers were injured. The fire contaminated the site and nearby areas of Paris with toxic dust and lead.
