9. Conflans-Sainte-Honorine to Bougival

The name of this dungeon would come from "Mons Jovis" (Mount Jupiter), designating the rocky spur on which it rests, ideal for watching over the Seine. Built at the end of the 11th century on the remains of a wooden fortification burnt down during a feudal war, this tower has imposing dimensions (15 metres high and three levels) and is a major element of the landscape of Vieux-Conflans. It is a precious witness of the first generation of stone castles in Île-De-France, one of the most beautiful specimens of a quadrangular Romanesque keep remaining in the region. Deprived of a roof in the 16th century, it remained the seat of the barony of Conflans until the Revolution. The west and south sides have geminated windows, very rare in the military architecture of that time. The tower was donated to the town in 1931 by the Cornudet family.

The important river activity explains the presence on the quays of barges "restaurant," or "theater", and also the barge "je sers". This barge built in concrete in 1919 was first used to transport coal. It became the headquarters of the mutual social assistance of the bargees in 1935, then the floating bargemen's chapel in 1936, and is now also a place of reception for migrants, especially Tibetans, since 2014. The nearby school was initially reserved for bargemen's children.

Situated on the Via Columbani in the state-owned forest of Saint-Germain-en-Laye, the Pavillon de la Muette is a remarkable testimony to French architecture of the late 17th century and is located at the crossroads of paths much frequented by walkers.
Built on the plans of Ange Jacques Gabriel, it was Louis XV's hunting lodge in Saint-Germain-en-Laye.
The west lounge on the main floor, the large octagonal north lounge as well as the two large underground kitchens of the Pavillon de la Muette are presented to you during the visit.
Why the name "La Muette"? The exact etymology would be the "mute" in reference to the packs of dogs during hunting parties.

An important part of your stage takes place in the state-owned forest of Saint-Germain-en-Laye.
Take advantage of this greenery before entering the suburbs near Paris.
With a current surface area of 3,540 hectares, the Saint-Germain national forest was very early on a hunting ground much appreciated by the kings of France and later by the emperors. Today, it is a forest much frequented by walkers, cyclists and horse riders. A total of three million visitors a year. This forest is listed as a classified wooded area (EBC) with a well identified natural zone: the pond of Corra. It is the second largest forest in the Yvelines after the Rambouillet forest.
About forty remarkable trees
These trees have been classified by the National Forestry Office (ONF) and the associations of the Friends of the Forest of Marly and Saint-Germain.
The forest is managed by the National Forest Office. Silvicultural interventions are necessary to guarantee, in the long term, a balanced, healthy and welcoming forest.

Visited by François I, Henri II, Louis XIV, Louis XV, the Maison du Val, also called the Maison de Carrières sous-bois (the current Château du Val), was originally one of the many hunting lodges in the forest of Saint-Germain-en-Laye.
It was during the first half of the reign of Louis XIV that the small hunting lodge began a second life. The king was looking for a place of residence close to Paris.
In January 1666, Louis XIV decided to leave Paris and made Saint-Germain-en-Laye his main place of residence. He left Saint-Germain-en-Laye definitively for Versailles in April 1682.
Around 1675, on the orders of Louis XIV, Jules Hardouin-Mansart replaced the simple "Maison du Val" with a small castle that completed the development of the walkway that made up the Great Terrace of Saint-Germain-en-Laye, where the King could find rest and solitude.
For Louis XIV, this relatively modest construction was an opportunity to test Hardouin-Mansart's talent.
The definitive transfer of the royal court to Versailles in 1682 led to the abandonment of the Château du Val, until Louis XV distributed successive patents to several "great families", notably to the Prince Marshal of France Charles Just de Beauvau-Craon and his second wife Marie-Charlotte Sylvie née Rohan.
In 1926, the Château du Val was sold by Count Oscar de Reinach-Cessac to Messrs Dumien and Lacoste. The latter, a legionnaire by title, decided to offer the château to General Dubail, Grand Chancellor of the Order of the Legion of Honour and founder of the SEMLH (Société d'Entraide des Membres de la Légion d'Honneur), in order to make it the retirement home of the Legion of Honour.

In 1897 the crib Sainte Marie was founded by Mr and Mrs Bouzemont, on a 6000 m2 plot of land belonging to them. They maintain at their own expense this institution run by nuns.
Still active until her death in 1931, after having donated it to the commune, Mrs Bouzemont was responsible for the maintenance and running of the crèche and the dispensary created for the sick children of Bougival. This building also bears the name of the Sainte-Marie crèche, but must keep, following the donation, the inscription "Fondation Bouzemont".
From 1915 to 1919 the Bouzemont Foundation was an auxiliary hospital of the French Red Cross. Soldiers wounded at the front found refuge there.
The Music Conservatory was founded in 1982, and permanently occupies the 5 rooms on the first floor,

The church of Notre-Dame de l'Assomption, built during the first half of the 12th century, was restored at the end of the 19th century by Lucien Magne, one of the architects of the Sacré-Cœur de Montmartre.
The 12th century bell tower is listed. The church has two capitals, also from the 12th century, placed at the entrance of the choir.
The baptismal font dates from the 16th century and the altar, carved in gilded wood, from the 17th century.
In the south aisle is the epitaph of Rennequin Sualem, inventor of the so-called Machine of Marly. Let us mention the Art Nouveau mosaics and the suite of stained-glass windows from the same period on the south side.
