Few cities carry as many stacked layers of history as Paris. The city began as a small settlement of the Gallic Parisii tribe on a small island in the Seine — what we know today as Île de la Cité — before the Romans took it over in the 1st century BC and turned it into the city of Lutetia. That small island remained the political and religious heart of Paris for centuries, and it's where Notre-Dame Cathedral stands today; construction began in 1163 and took more than 180 years to complete, making it one of the great achievements of Gothic architecture in the world. It reopened its doors in December 2024 after a massive restoration following the devastating 2019 fire.

Through the Middle Ages, Paris gradually grew into one of Europe's largest cities and most important intellectual centers, especially after the founding of the Sorbonne in the 13th century, which turned the surrounding Latin Quarter into a hub of thought, theology, and philosophy — a character it still carries today.

The 19th century marked a radical turning point, when Emperor Napoleon III commissioned Baron Haussmann to completely redesign the city between 1853 and 1870, tearing down cramped poor neighborhoods and replacing them with the broad boulevards and uniform stone buildings that define the classic "Parisian style" every visitor sees on the city's streets today. Around this period, Paris also began earning the nickname "the City of Light" (la Ville Lumière), partly because it was among the first major cities to widely adopt public street lighting, and partly thanks to its status as a European beacon of thought and enlightenment.

In 1889, for the World's Fair, the Eiffel Tower was built to Gustave Eiffel's design. It was initially highly controversial — many Parisians considered it a disfigurement of the skyline — before becoming, within just a few decades, the single most recognizable symbol of France.

In the early 20th century, Paris became a global capital of modern art, drawing artists and writers from around the world — from Picasso to Hemingway — who lived and created in neighborhoods like Montmartre and Montparnasse during an era often called "les Années folles" (the crazy years). That artistic legacy remains powerfully present in the city's great museums — the Louvre, Orsay, and Pompidou.

Today, Paris is a unique blend of stacked historical layers — Roman, medieval, classical, and modern — coexisting side by side in a single urban fabric, which is exactly what makes walking through it feel like reading an open history book.
