Paris in Layers: How Five Centuries of Power Left the City We Walk

Most cities are read as a skyline. Paris is read as a section. Cut down through it anywhere and you find not one city but several, laid on top of each other by different regimes, each of which wanted the stone to say something about who held power and why. The reason Paris feels coherent is that each layer was ambitious enough to reach for the whole city, and the reason it feels endless is that none of them ever fully erased the one before.

Here is the stack, bottom to top, and how to walk each one.

Layer one: the royal square

The oldest deliberate image of power a walker can still stand inside is the Place des Vosges, built by Henri IV between 1605 and 1612 as the Place Royale. It is the oldest planned square in the city: thirty-six brick-and-stone houses to a single uniform design, a true 140-metre square, arcades all the way around. The idea was radical for its moment. A king would impose one architecture on a whole public space and invite the aristocracy to live inside the picture. This is the ancestor of every uniform façade Paris would later be famous for. The Marais grew up around it as the aristocratic quarter, packed with hôtels particuliers, the private mansions of the seventeenth-century Bourbon elite.

Layer two: the city of ideas

Older still in institution, if not in surviving stone, is the intellectual Paris of the Left Bank. The Collège de la Sorbonne was founded by Robert de Sorbon, chaplain to Louis IX, around 1253 and confirmed by the king in 1257. The neighborhood answered a specific question architecturally: where do ideas come from, and who is allowed to make them. The answer was a chartered institution on the Montagne Sainte-Geneviève, and the Latin Quarter has been arguing the same question ever since, from the medieval schoolmen to Sartre to the paving-stone barricades of May 1968. The Panthéon on the hilltop is the clearest single object of this layer: a church begun for Sainte-Geneviève, converted by revolutionary decree in April 1791 into a secular temple for the nation's great men.

Layer three: the imperial rebuild

The layer most visitors mistake for all of Paris is Baron Haussmann's. Appointed prefect of the Seine on 22 June 1853, Georges-Eugène Haussmann spent seventeen years driving wide boulevards through the medieval fabric on the orders of Napoleon III. His administration demolished roughly 19,730 buildings and built around 34,000, laying sewers, water, and gas beneath the new axes in parallel. He fixed the building grammar by decree: cream limestone, aligned cornices, ironwork balconies on the second and fifth floors, mansard roofs. When you photograph a "typically Parisian" street, you are almost always photographing this layer, not an old one. The Haussmann axes tour reads the grammar specimen by specimen, up to the Palais Garnier that anchors the whole system. Haussmann was dismissed on 5 January 1870 when parliament balked at the roughly 2.5 billion gold francs of opaque financing, but the code outlived him and still rules the city.

Layer four: the city of the people

Haussmann's boulevards pushed the poor uphill and outward. The working-class and immigrant city concentrated on the eastern hills, and its capital is Belleville. This is where the 1871 Paris Commune made its last stand: the final barricade fell on rue Ramponeau at around one in the afternoon on 28 May 1871, within a kilometre of the wall in Père Lachaise where the last Communards were shot. A century later the same slope absorbed the post-colonial migration of France, from Algeria, Tunisia, Senegal and Mali, alongside the Wenzhou Chinese who built Paris's second Chinatown here from the late 1970s. The layer is not stone but pattern: the same hill kept being the place where the question of who counts as French, or as a citizen at all, was fought out.

Layer five: the republic in glass

The newest deliberate layer belongs to one man. Between 1981 and 1995, President François Mitterrand executed the Grands Travaux, the most expensive single-presidency building program in postwar Europe. I. M. Pei's glass pyramid rose in the Cour Napoléon of the Louvre, inaugurated on 29 March 1989; Jean Nouvel's Institut du Monde Arabe wrapped a modern Arab-world cultural center in a photosensitive metal skin that quotes the mashrabiya; the Opéra Bastille placed a people's opera on the exact site where the Bastille prison fell in 1789. Each building is an argument about what a republic should say about itself in the late twentieth century, made in glass and steel rather than limestone.

How to read the stack yourself

You do not have to hold all five layers in your head at once, and you should not try to. The mistake most Paris itineraries make is treating the city as a checklist of monuments with no argument connecting them. Read one layer per walk instead. Spend an afternoon in the Marais and you read the royal and aristocratic city, then the Jewish city stacked on top of it. Walk the Haussmann spine and the uniformity stops being wallpaper and becomes a legible system. Climb Belleville and the postcard city drops away entirely.

Each Roamer Paris tour is built around one of these arguments rather than around a list of sights. That is the whole design: not to show you Paris, but to hand you the reading key so the city explains itself.
