That eighteenth-century mansion with the rotunda looking on to the Seine, opposite the Musée d’Orsay, is not a ministry, although it looks exactly like one: there are two sphinxes on either side of the steps and inside is the Grande Chancellerie of the Légion d’honneur, the administration of the order founded by Napoleon. In the wing of the old stables, though, there is a museum you can visit free of charge.
It holds around five thousand objects: insignia, paintings, uniforms, weapons and decorations from half the world. It is the place where you grasp something we usually take for granted: why states pin pieces of metal to people’s chests.
The only real constraint is the opening hours, and they are tight: the museum opens only in the afternoon, Wednesday to Sunday, 13:00-18:00, with the last admission half an hour before. On Thursday it carries on until 20:00. I would fit it in with the Orsay, which is across the road and opens in the morning: they are the two easiest museums in the whole of Paris to put into the same day.
Why did an American ambassador come every day to look at this building?
Let’s go!
1. The hôtel de Salm, and the diplomat who fell in love
The land was bought on 12 July 1782 by a German prince, Frédéric III de Salm-Kyrbourg, and the house was designed by the architect Pierre Rousseau. The result is one of the most admired buildings of pre-revolutionary Paris: a low, severe front towards the street, and towards the Seine a rotunda with Corinthian columns under a dome.
One of its admirers is a man you know. Thomas Jefferson, United States ambassador in Paris from 1785 to 1789, wrote that he had been «violently smitten» with it, and said he went to the Tuileries almost every day to look at it. This is not a piece of gossip. Back in Virginia, Jefferson remodelled his own house at Monticello by adding a low dome over a central block: that is the model he had been looking at for four years from the other bank of the Seine, because the Tuileries from which he watched it are directly opposite.
2. How a private house becomes the home of an order
Why is the Légion d’honneur based precisely here?
Because it bought the place. Napoleon created the order in 1802, and the Légion d’honneur bought the hôtel de Salm on 13 May 1804 for a little over three hundred thousand francs, installing the Grande Chancellerie in it. It has not moved since, and that continuity of more than two centuries is the reason the collection is what it is: it was not put together by a collector, it grew inside the institution that produced it.
3. The fire of the Commune, and the rebuilding the decorated paid for
In May 1871, during the final week of the Commune, the house was set on fire along with the palais d’Orsay next door, and burnt almost entirely. Much of what you see today is therefore rebuilding: the architect François Athanase Mortier took it on, and the works finished in 1875.
The detail worth taking away is how it was paid for: by a subscription among the members of the order. The decorated put the house of their own decoration back on its feet, which is at once a piece of accounting news and the definition of what an order of chivalry is.
The state rooms of the house can be visited too, and the finest of them is the salon de l’Aurore, which takes its name from the painted ceiling.
4. The museum an American lawyer paid for
The museum was founded in 1925, after the First World War, at the wish of the grand chancellor General Dubail, who had the wing of the old stables turned into galleries: when you walk into the museum, then, you are walking where the horses stood. Much of the funding came, through a series of gifts, from the American business lawyer William Nelson Cromwell.
From then on the museum grew in bursts: it expanded in 1932 to take in the foreign orders, and it doubled its exhibition space in 2006, for the bicentenary of the Légion d’honneur. The route you walk now was rearranged between 2016 and 2018.
5. Before Napoleon: the knights and the kings
What did people who deserved a reward receive before medals existed?
The route does not begin with the Légion d’honneur, and it is right not to. The first section is given to the orders of chivalry and religious orders, the medieval ones: the Order of Saint John of Jerusalem, in other words Malta, the Teutonic order and that of the Holy Sepulchre.
Then come the French royal orders: Saint Michael, the Holy Spirit, Saint Louis. If you look at the insignia side by side you see the shift: it starts with crosses that declare a religious vow and ends with crosses that declare a service rendered to the king. The modern decoration is born in the middle of that change of meaning.
6. The room of the Légion d’honneur, and the Empire
The heart of the museum is the room given to the Légion d’honneur and to the imperial orders, with the armes d’honneur that Napoleon handed out even before he created the order, and the insignia of the Order of the Iron Crown and the Order of the Reunion.
Napoleon’s idea was exactly this: a reward that anyone could receive, soldier or civilian, noble or not, in a country that had just abolished the privileges of birth. These cases show you in two minutes how widely that idea was copied, because almost every state in the world has taken it up.
The route goes on with the salle de l’Empereur and the salle des Frères, and closes on contemporary decorations, as far as the Ordre national du Mérite and the national medal of gratitude for the victims of terrorism.
One of the rooms you pass through is the salon des grands chanceliers: the oval portraits of the chancellors who followed one another frame a case of weapons and decorations, and the room says in one go what an order is, a chain of people handing on an office.
7. The Spada room, and the 122 states
The last stop is the one you do not expect in a French museum, and it arrived in 2008 with the gift of the collection of the Italian Antonio Benedetto Spada, the greatest collector of orders and decorations in the world.
The room that carries his name holds more than four hundred orders and decorations from 122 states, existing and vanished. Stop and read the labels and you will notice that the matter has stopped being French and become anthropological: monarchies and republics, dissolved empires, countries born in the 1960s, all of them hanging coloured enamels from a ribbon according to the same rules.

The address is 2 rue de la Légion d’honneur, in the seventh arrondissement, opposite the Musée d’Orsay. The stops are Solférino on line 12 and Musée d’Orsay on the RER C. How long it takes. The route asks for an hour and a half, and it goes well with a morning at the Orsay, which is across the road.
Where to go from here
Across the road is the Musée d’Orsay, and the Musée Rodin and the Musée de l’Armée at the Invalides are a quarter of an hour on foot: the last of those tells the same military history from the side of the weapons instead of the decorations. On the other bank, the Monnaie de Paris has been striking the medals of the French state since the eighteenth century, and it is the craft the objects in this museum come out of. If you are interested in how power has told its own story through buildings, the Conciergerie and the Panthéon are the two chapters that are missing here: the palace the kings governed from, and the temple the Republic built for itself.
