The Mysterious Plaque That Connects All of France’s Roads

The Kilometer Zero plaque in Paris is a small but fascinating landmark. It is located in front of the Notre-Dame Cathedral, right in the middle of the square called Place Jean-Paul II. Many people walk past it without noticing its importance.

The plaque is easy to find if you know where to look. Stand in front of Notre-Dame Cathedral and look down at the square. It’s near the middle of the pavement. Tourists often stop to take pictures or make a wish while standing on the plaque.

What Is Kilometer Zero?

Kilometer Zero is the official starting point for measuring distances in France. Every road in the country is connected to this spot. When you see a road sign saying, for example, “Paris 200 km,” the distance is measured from this plaque.

The plaque itself is a bronze marker set in the pavement. It shows a star design and the words “Point Zéro des Routes de France” (Kilometer Zero of France’s Roads).

Besides being a starting point, Kilometer Zero is a symbol of how roads connect the entire country. It also shows the influence of Paris as the central hub of France. Even today, it serves as a reference point for maps, routes, and calculations.

The idea of Kilometer Zero traces back to ancient Rome, where all roads were measured from the Milliarium Aureum (Golden Milestone) in the Roman Forum. This system symbolized Rome’s dominance as the center of its empire. France adopted a similar concept centuries later, reflecting its centralized structure, with Paris as the heart of the country.

Before the installation of the current plaque in 1924, the reference point for French roads wasn’t standardized. Distances were sometimes calculated from the Paris Observatory, an important scientific landmark, or from local city centers. These inconsistencies made navigation and measurement less precise.

Notre-Dame had long been considered the spiritual and geographical center of Paris, even before the plaque was installed. By placing Kilometer Zero here, it reinforced the cathedral’s significance as a symbol of Paris and its central role in France.

Over the years, this small plaque has become more than a practical tool for measuring distances. It represents France’s strong sense of national unity, connecting every road in the country to one definitive point.

While modern navigation systems no longer rely on physical markers, Kilometer Zero remains an enduring symbol of France’s history and Paris’s importance as the nation’s hub.

Many visitors believe that standing on the Kilometer Zero plaque brings good luck. It’s also become a popular spot for couples, who see it as a romantic symbol of starting their journey together and often share a kiss there.

Visitors often leave coins at the center of the Kilometer Zero plaque as a gesture of good luck or to make a wish. This tradition isn’t officially tied to the plaque’s history, but it has grown over time, much like tossing coins into fountains.

Some believe that leaving a coin on the plaque ensures a safe return to Paris or brings good fortune for future travels. Others see it as a symbolic connection to the heart of France, leaving a small part of themselves at this central point.

Interestingly, while many countries have their own Kilometer Zero points, the one in Paris is among the most well-known. Curious travelers want to stand at the heart of France’s road network.
