The Basilica and Cathedral of Saint-Étienne in Paris, on the Île de la Cité, was an early Christian church that preceded Notre-Dame de Paris. It was built in the 4th or 5th century, directly in front of the location of the modern cathedral, and just 250 meters from the royal palace. It became one of the wealthiest and most prestigious churches in France. Nothing remains above the ground of the original cathedral. It was demolished beginning in about 1163, when construction began on Notre-Dame de Paris. Vestiges of the foundations remain beneath the pavement of the square in front of Notre-Dame and beneath the west front of the cathedral. The church was built and rebuilt over the years in the Merovingian, Carolingian and Romanesque architectural styles.

Sainte-Geneviève-des-Ardents (French pronunciation: ​[sɛ̃t ʒə.nə.vjɛv də.z‿aʁ.dɑ̃]), known as Sainte-Geneviève-la-Petite in the Middle Ages, was a church located at present-day Parvis Notre-Dame – Place Jean-Paul-II in the Île de la Cité in Paris, France. It is dedicated to Saint Genevieve, the miracles imputed to whom included "the cessation of a horrible plague, called the mal ardent, which desolated Paris in the reign of Louis le Gros".

The Church of Saint-Jean-le-Rond, Paris (Église Saint-Jean-le-Rond de Paris) was a small church originally attached to the north side of the Cathedral of Notre-Dame de Paris near the west front, and close to the entrance of the cloister. It was built earlier than Notre-Dame, at about the same time as the church which preceded Notre-Dame, the Cathedral of Saint-Etienne. It was dedicated to John the Baptist, and was used primarily as a baptistry. It survived centuries longer than the Cathedral of Saint Etienne, but was finally demolished in the early 18th century to make room for a new street, the rue du Cloître-Notre-Dame.

The Roman Catholic Archdiocese of Paris (Latin: Archidioecesis Parisiensis; French: Archidiocèse de Paris) is one of twenty-three archdioceses of the Catholic Church in France. The original diocese is traditionally thought to have been created in the 3rd century by St. Denis and corresponded with the Civitas Parisiorum; it was elevated to an archdiocese on October 20, 1622. Before that date the bishops were suffragan to the archbishops of Sens.

The Hôtel-Dieu (French pronunciation: ​[otɛldjø]) is a hospital located on the Île de la Cité in the 4th arrondissement of Paris, on the parvis of Notre-Dame. It was supposedly founded by Saint Landry in 651 AD, making it the oldest hospital in the city and the oldest worldwide still operating. The Hôtel-Dieu was the only hospital in the city until the Renaissance. While the old Hôtel-Dieu stood by the Seine on the opposite side of the parvise, it was ravaged by fire several times, and was rebuilt for the last time at its present location between 1867 and 1878, as part of Haussmann's renovation of Paris. Nowadays operated by Assistance publique – Hôpitaux de Paris (AP-HP), the Hôtel-Dieu is also a teaching hospital associated with the Faculté de Médecine Paris-Descartes.

The Bouquinistes of Paris, France, are booksellers of used and antiquarian books and rare vintage postcards who ply their trade along large sections of the banks of the Seine: on the right bank from the Pont Marie to the Quai du Louvre, and on the left bank from the Quai de la Tournelle to Quai Voltaire. The Seine is thus described as 'the only river in the world that runs between two bookshelves'.

The Petit Pont (Little Bridge) is a bridge crossing the River Seine in Paris, built in 1853, although a structure has crossed the river at this point since antiquity. The present bridge is a single stone arch linking the 4th arrondissement and the Île de la Cité, with the 5th arrondissement, between quai de Montebello and quai Saint-Michel. The Petit Pont is notable for having been destroyed, at least thirteen times since its original inception during Gallo-Roman times to the mid-19th century. It is served by the Metro station Saint-Michel.

The siege of Paris of 885–886 was part of a Viking raid on the Seine, in the Kingdom of the West Franks. The siege was the most important event of the reign of Charles the Fat, and a turning point in the fortunes of the Carolingian dynasty and the history of France. It also proved for the Franks the strategic importance of Paris at a time when it also was one of the largest cities in West Francia. The siege is the subject of an eyewitness account in the Latin poem Bella Parisiacae urbis of Abbo Cernuus. With hundreds of ships, and possibly tens of thousands of men, the Vikings arrived outside Paris in late November 885, demanding tribute. This was denied by Odo, Count of Paris, despite the fact he could assemble only several hundred soldiers to defend the city. The Vikings attacked with a variety of siege engines but failed to break through the city walls despite days of intense attacks. The siege was maintained for months but without any significant assaults after the initial attack. As the siege continued, most of the Vikings left Paris to pillage further upriver. The Vikings made a final unsuccessful attempt to take the city during the summer. In October, Charles the Fat arrived with his army. To the frustration of the Parisians who had fought to defend the city, Charles stopped short of attacking the Viking invaders. Instead, he allowed them to sail further up the Seine to raid Burgundy (which was in revolt) and promised a payment of 700 livres (257 kg) of silver. Odo, highly critical of this, attempted to defy Charles' promises. When Charles died in 888, Odo was elected the first non-Carolingian king of the Franks.

Notre-Dame de Paris (French: [nɔtʁə dam də paʁi] (listen); meaning "Our Lady of Paris"), referred to simply as Notre-Dame, is a medieval Catholic cathedral on the Île de la Cité (an island in the Seine River), in the 4th arrondissement of Paris. The cathedral, dedicated to the Virgin Mary, is considered one of the finest examples of French Gothic architecture. Several of its attributes set it apart from the earlier Romanesque style, particularly its pioneering use of the rib vault and flying buttress, its enormous and colourful rose windows, and the naturalism and abundance of its sculptural decoration. Notre Dame also stands out for its musical components, notably its three pipe organs (one of which is historic) and its immense church bells.Construction of the cathedral began in 1163 under Bishop Maurice de Sully and was largely completed by 1260, though it was modified frequently in the centuries that followed. In the 1790s, during the French Revolution, Notre-Dame suffered extensive desecration; much of its religious imagery was damaged or destroyed. In the 19th century, the coronation of Napoleon I and the funerals of many of the French Republic's presidents took place at the cathedral. The 1831 publication of Victor Hugo's novel Notre-Dame de Paris (known in English as The Hunchback of Notre-Dame) inspired popular interest in the cathedral, which led to a major restoration project between 1844 and 1864, supervised by Eugène Viollet-le-Duc. During World War II, after the Allies' 1944 victory in Europe, the liberation of Paris was celebrated in Notre-Dame with the singing of the Magnificat. Beginning in 1963, the cathedral's façade was cleaned of centuries of soot and grime. Another cleaning and restoration project was carried out between 1991 and 2000.The cathedral is one of the most widely recognized symbols of the city of Paris and the French nation. In 1805, it was awarded the honorary status of a minor basilica. As the cathedral of the archdiocese of Paris, Notre-Dame contains the cathedra of the archbishop of Paris (Michel Aupetit). Approximately 12 million people visit Notre-Dame annually, making it the most visited monument in Paris. The cathedral has long been renowned for its Lent sermons, a tradition founded in the 1830s by the Dominican Jean-Baptiste Henri Lacordaire. In recent years, these sermons have increasingly often been given by leading public figures or government-employed academics. Over time, the cathedral has gradually been stripped of many of its original decorations and artworks. However, the cathedral still contains several noteworthy examples of Gothic, Baroque, and 19th-century sculptures, a number of 17th- and early 18th-century altarpieces, and some of the most important relics in Christendom – including the Crown of Thorns, a sliver of the true cross and a nail from the true cross. On 15 April 2019, while Notre-Dame was undergoing renovation and restoration, its roof caught fire and burned for about 15 hours. The cathedral sustained serious damage as a result. The flèche (the timber spirelet over the crossing) was destroyed, as was most of the lead-covered wooden roof above the stone vaulted ceiling. This resulted in contamination of the site and the nearby environment with lead. After the fire, many of the proposals for restoration suggested modernizing the cathedral's design, but the French National Assembly rejected this approach, enacting a law on 29 July 2019 that required the restoration to preserve the cathedral's “historic, artistic and architectural interest”. The task of stabilizing the building against possible collapse was completed in November 2020, and reconstruction began in 2021. The government of France has said it hopes the reconstruction can be completed by Spring 2024, in time for the opening of the 2024 Summer Olympics in Paris. President Emmanuel Macron confirmed on 14 April 2021 that the cathedral site will be formally returned to the church on 15 April 2024, and that the first mass since the fire will be held in the cathedral nave on that day, even if the reconstruction has not been finished by then.

On 4 September 2016, a car containing seven canisters of gas and pages with Arabic writing was found parked near Notre-Dame de Paris cathedral in Paris.

The siege of Paris of 845 was the culmination of a Viking invasion of West Francia. The Viking forces were led by a Norse chieftain named "Reginherus", or Ragnar, who tentatively has been identified with the legendary saga character Ragnar Lodbrok. Reginherus's fleet of 120 Viking ships, carrying thousands of men, entered the Seine in March and sailed up the river. The Frankish king Charles the Bald assembled a smaller army in response but after the Vikings defeated one division, comprising half of the army, the remaining forces retreated. The Vikings reached Paris at the end of the month, during Easter. They plundered and occupied the city, withdrawing after Charles the Bald paid a ransom of 7,000 French livres [2,570 kg (83,000 ozt)] in gold and silver.
