Île de la Cité in the context of "Notre-Dame Cathedral"

The 1st arrondissement of Paris (I arrondissement) is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is colloquially referred to as le premier (the first). It is governed locally together with the 2nd, 3rd and 4th arrondissement, with which it forms the 1st sector of Paris (Paris-Centre).

Also known as Louvre, the arrondissement is situated principally on the right bank of the River Seine. It also includes the west end of the Île de la Cité. The locality is one of the oldest areas in Paris, the Île de la Cité having been the heart of the city of Lutetia, conquered by the Romans in 52 BC, while some parts on the right bank (including Les Halles) date back to the early Middle Ages.

Notre-Dame de Paris (French: Cathédrale Notre-Dame de Paris French: [nɔtʁ(ə) dam də paʁi] : "Cathedral of Our Lady of Paris"), often referred to simply as Notre-Dame, is a medieval Catholic cathedral on the Île de la Cité (an island in the River Seine), in the 4th arrondissement of Paris, France. It is the cathedral church of the Roman Catholic Archdiocese of Paris.

The cathedral, dedicated to the Virgin Mary ("Our Lady"), is considered one of the finest examples of French Gothic architecture. Several attributes set it apart from the earlier Romanesque style, including 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 is also exceptional for its three pipe organs (one historic) and its immense church bells.

The Sainte-Chapelle (French: [sɛ̃t ʃapɛl]; English: Holy Chapel) is a royal chapel in the Gothic style, within the medieval Palais de la Cité, the residence of the Kings of France until the 14th century, on the Île de la Cité in the River Seine in Paris, France.

Construction began sometime after 1238 and the chapel was consecrated on 26 April 1248. The Sainte-Chapelle is considered among the highest achievements of the Rayonnant period of Gothic architecture. It was commissioned by King Louis IX of France to house his collection of Passion relics, including Christ's claimed Crown of Thorns – one of the most important relics in medieval Christendom. This was later held in the nearby Notre-Dame Cathedral until the 2019 fire, which it survived.

The Pont Neuf (French pronunciation: [pɔ̃ nœf], "New Bridge") is the oldest standing bridge across the river Seine in Paris, France. It stands by the western (downstream) point of the Île de la Cité, the island in the middle of the river that was, between 250 and 225 BC, the birthplace of Paris, then known as Lutetia and, during the medieval period, the heart of the city.

The bridge is composed of two separate spans, one of five arches joining the left bank to the Île de la Cité, another of seven joining the island to the right bank. Old engraved maps of Paris show that the newly built bridge just grazed the downstream tip of the Île de la Cité; since then, the natural sandbar building of a mid-river island, aided by stone-faced embankments called quais, has extended the island. Today the tip of the island is the location of the Square du Vert-Galant, a small public park named in honour of Henry IV, nicknamed the "Green Gallant".

The 4th arrondissement of Paris (IV arrondissement) is one of the twenty arrondissements of Paris, the capital city of France. In spoken French, this arrondissement is referred to as quatrième. Along with the 1st, 2nd and 3rd arrondissements, it is in the first sector of Paris, which maintains a single local government rather than four separate ones.

The arrondissement, also known as Hôtel-de-Ville, is situated on the right bank of the River Seine. It contains the Renaissance-era Paris City Hall, rebuilt between 1874 and 1882. It also contains the Renaissance square of Place des Vosges, the overtly modern Pompidou Centre, and the lively southern part of the medieval district of Le Marais, which today is known for being the gay district of Paris. (The quieter northern part of Le Marais is within the 3rd arrondissement). The eastern part of the Île de la Cité (including Notre-Dame de Paris) and all of the Île Saint-Louis are also included within the 4th arrondissement.

The Parlement of Paris (French: Parlement de Paris) was the oldest parlement in the Kingdom of France, formed in the 14th century. Parlements were judicial, rather than legislative, bodies and were composed of magistrates. Though not representative bodies in the present sense of the word, they had procedures and authorities that could delay the otherwise unchecked power of the King. Because of its location and history, the Parlement of Paris was the most significant. The Parlement of Paris was established under Philip IV of France in 1302. The Parlement of Paris would hold sessions inside the medieval royal palace on the Île de la Cité, which today is the site of the Paris Hall of Justice.

The Pillar of the Boatmen (French: Pilier des nautes) is a monumental Roman column erected in Lutetia (modern Paris) in honour of Jupiter by the guild of boatmen in the 1st century AD. It is the oldest monument in Paris and is one of the earliest pieces of representational Gallo-Roman art to carry a written inscription.

The Roman name for the monument is Nautae Parisiaci (the sailors of the Parisii, who were a tribe of Gauls). It was found re-used in the 4th century city wall on the Île de la Cité and is now displayed in the frigidarium of the Thermes de Cluny.

The Palais de la Cité (French pronunciation: [palɛ d(ə) la site]), located on the Seine River's Île de la Cité, is a major historic building in the centre of Paris, France. It was an occasional residence of the Kings of France from the early 6th to the 12th century and a permanent one from the late 12th to the 14th century, and has been the center of the French justice system ever since, for which it is also referred to as the Palais de Justice.

From the 14th century until the French Revolution, the Palais was the headquarters of the Parlement of Paris. During the Revolution it served as a courthouse and prison, where Marie Antoinette and other prisoners were held and tried by the Revolutionary Tribunal. Since the early 19th century, it has been the seat of the Tribunal de grande instance de Paris, the Court of Appeal of Paris, and the Court of Cassation. The first of these moved to another Parisian location in 2018, while the latter two jurisdictions remain located in the Palais de la Cité as of 2025.
