Chalais-Meudon

Meudon Castle, also known as the Royal Castle of Meudon or Imperial Palace of Meudon, is a French castle located in Meudon in the Hauts-de-Seine department. At the edge of a wooded plateau, the castle offers views of Paris and the Seine, as well as of the Chalais valley. Located between Paris and Versailles, in the heart of a hunting reserve, the castle has an ideal topography for large gardens. It had many successive owners from the Renaissance until the fall of the Second French Empire. It should not be confused with the Bellevue Castle, also located in Meudon. Famous past residents include: Anne de Pisseleu d'Heilly, Duchess of Étampes; the Cardinal of Lorraine, Abel Servien; François Michel Le Tellier, Marquis of Louvois and Louis, Grand Dauphin, also known as Monseigneur, who linked the Chaville Castle to Meudon Castle. The Château-Vieux (Old Castle) burned down in 1795 and was rebuilt as the Château-Neuf (New Castle), which in turn burned down in 1871. Demolition was considered, but most of the castle was preserved and became an observatory with an astronomical telescope in 1878 and was then attached to the Observatory of Paris in 1927. The castle of Meudon has been classified as a historical monument since 12 April, 1972. Hangar Y in the Chalais-Meudon park has been classified as an historical monument since 4 June 2000. It was the first storage facility for aerostats in the world and is one of the few still standing.

Meudon Great Refractor (also known as the Grande Lunette) is a double telescope with lenses (83 cm + 62 cm), in Meudon, France. It is a twin refracting telescope built in 1891, with one visual and one photographic, on a single square-tube together on an equatorial mount, inside a dome. The Refractor was built for the Meudon Observatory, and is the largest double doublet (twin achromat) refracting telescope in Europe, but about the same size as several telescopes in this period, when this style of telescope was popular. Other large telescopes of a similar type include the James Lick telescope (91.4), Potsdam Great Refractor (80+50 cm), and the Greenwich 28 inch refractor (71.1 cm). Institutionally it was part of the Meudon Observatory, which later became integrated with the Paris observatory. The Great Refractor was used for research well into the 1980s, after nearly a century of use. In the 21st century it was renovated and re-opened for public outreach. The telescope is noted for being used to disprove the theory of Martian canals, which was a popular story in the late 19th century. The telescope lenses were made by the Henry Brothers, and the mounting was made by Gautier.

Meudon (French pronunciation: [mødɔ̃] (listen)) is a municipality in the southwestern suburbs of Paris, France. It is in the département of Hauts-de-Seine. It is located 9.1 km (5.7 mi) from the center of Paris. The city is known for many historic monuments and some extraordinary trees. One of them, the Imperial Cedar (Cèdre Impérial), attracted the attention of Empress Eugénie and Queen Victoria. As of March 2021, the tree is in good condition, but it is threatened by real estate speculation. Another real estate project is planned for the historic park of the Napoleon III villa built by Charles Schacher. Both projects are controversial and have aroused local opposition.

On 8 May 1842, a train crashed in the cutting between Meudon and Bellevue stations on the railway between Versailles and Paris, France. The train was travelling to Paris when it derailed after the leading locomotive broke an axle, and the carriages behind piled into it and caught fire. It was the first French railway accident and the deadliest in the world at the time, causing between 52 and 200 deaths, including that of explorer Jules Dumont d'Urville. The accident led the French to abandon the practice of locking passengers in their carriages. Metal fatigue was poorly understood at the time and the accident led to systematic research into the problem.

The Château de Bellevue (French: [ʃɑto də bɛlvy]) was a small château built for Madame de Pompadour in 1750. It was constructed on a broad plateau in Meudon, above a slope overlooking the Seine to the east, but was demolished in 1823 and little remains.

Île Seguin (Seguin Island) is an island on the Seine river between Boulogne-Billancourt and Sèvres, in the west suburbs of Paris, France. It has a surface area of approximately 11.5 hectares (28 acres), and is positioned opposite Meudon, a short distance downstream from the Île Saint-Germain. Administratively Meudon and the island are included as part of Boulogne-Billancourt, on the river's right bank, rather than of Sèvres on the left bank. During most of the twentieth century, Île Seguin was home to a Renault factory, covering virtually the whole island. The last car from the Renault production line was a 1992 Renault 5 Supercinq. The factory remained dormant until 2005 when all the buildings were demolished. The architect Jean Nouvel was appointed in 2009 as the lead planner to transform the island into a new cultural hub. The first permanent concert and performance spaces in the project, known as La Seine Musicale, were opened in April 2017. Hotels, large offices, art spaces, and a cinema will follow.
