You’re standing in St. Peter’s Square. The sun is hitting the cobblestones, and you hear a flurry of voices. It’s a weird mix. You might hear a Swiss Guard shouting in German, a priest whispering in Polish, or a tour guide explaining architecture in English. But when people ask what language do they speak in the Vatican, they usually want a single, clean answer.
It’s not that simple. Honestly, the Vatican is probably the most linguistically confusing half-square-kilometer on the planet.
If you look at the official documents, Latin is king. It’s the "official" language of the Holy See. But if you walk into the Vatican grocery store (the Annona) and try to order milk in Latin, the clerk will probably just stare at you until you switch to Italian. That’s the reality of the world’s smallest country. It’s a place where ancient tradition hits the brick wall of modern daily life.
The Italian Reality of the Holy See
Most people assume everyone is walking around chanting in Latin. They aren't. In every practical sense, the day-to-day language of Vatican City is Italian.
Why? Because the Vatican is an enclave inside Rome. The people who work there—the janitors, the electricians, the restorers in the Vatican Museums—are mostly Italian citizens. They live in Rome. They eat pasta in Prati. They talk about football. When the Gendarmerie (the Vatican police) pulls someone over or directs traffic, they do it in Italian.
Even the laws of the Vatican City State are published in Italian. While the "Holy See" (the religious entity) uses Latin for its high-level business, the "Vatican City State" (the physical territory) runs on the language of Dante. If you go to the Vatican post office to buy those famous stamps, you’re using Italian. It’s the glue that holds the place together.
It’s funny, actually. The Vatican is the only place in the world where an ATM will give you instructions in Latin. You’ll see "Insere scidulam quaeso ut faciundum cognoscas" on the screen. It’s a novelty. A flex. But the guy standing behind you in line is definitely cursing under his breath in a Roman accent because the line is moving too slow.
But What About Latin?
So, is Latin dead? Not exactly. It’s more like it’s on life support in a very expensive, gilded room.

The Catholic Church uses Latin as its universal language. This is practical. If you have a bishop from South Korea, one from Brazil, and one from Nigeria, they need a common tongue that doesn't belong to a specific modern superpower. Latin is "neutral."
When the Pope issues an Encyclical—a major letter to the world—the "typical" or authoritative version is almost always in Latin. The Latinitas Foundation, which was established by Pope Paul VI, actually works to keep the language alive. They even create new words for modern things. How do you say "Internet" in Latin? Rete informaticum. What about a "computer"? Instrumentum computatorium.
They take this stuff seriously. There is a whole office in the Secretariat of State called the Office of Latin Letters. These guys are the elite. They translate the Pope’s tweets (yes, @Pontifex has a Latin account) and ensure that every official decree is grammatically perfect. But even they probably go out for pizza and speak Italian at lunch.
The Swiss Guard and Their Secret Language
Here is where it gets even more complicated. If you see the guys in the bright blue, red, and orange striped uniforms, you’re looking at the Pontifical Swiss Guard.
To be a Swiss Guard, you have to be a Swiss citizen. Most of Switzerland speaks German (or a specific dialect called Swiss German). Consequently, the command language for the Pope's army is German. When they are at the barracks or training, you’ll hear a lot of "Achtung."
However, they are also required to learn Italian so they can talk to the public and the other Vatican employees. It’s a polyglot’s dream. Or nightmare. Imagine being a 20-year-old recruit from Zurich trying to navigate a legal system written in Italian while your boss gives you orders in German and your church service is in Latin.
The Language of Diplomacy
The Vatican isn’t just a church; it’s a diplomatic powerhouse. It has "nuncios" (ambassadors) in almost every country.

In the world of international diplomacy, the Holy See often uses French. For a long time, French was the global language of treaties and negotiations. While English has taken over most of the world, the Vatican holds onto tradition. When a new ambassador presents their "letters of credence" to the Pope, the formal exchange often involves French.
What Language Does the Pope Speak?
Pope Francis is an interesting case. He’s from Argentina, so his native tongue is Spanish. He’s also of Italian descent, so his Italian is basically perfect, though with a slight accent.
Unlike his predecessor, Benedict XVI, who was a world-class linguist comfortable in German, Latin, French, and English, Francis tends to stick to Italian for almost everything. Even when he’s traveling to places like the United States or the Philippines, he often gives his main speeches in Italian or Spanish and has a translator read the English version.
He’s a man of the people, and for him, Italian is the language of his "flock" in the Diocese of Rome. It’s intimate. It’s direct.
Breaking Down the Language Stats (Sorta)
There isn't a census that says "40% speak this, 20% speak that." The population is only about 450 to 800 people depending on who you count. But we can categorize the usage like this:
Official State Business: Italian.
Ecclesiastical (Church) Law: Latin.
The Swiss Guard: German and Italian.
Diplomacy: French, English, and Spanish.
The "Street" Language: Italian.
If you’re a tourist, you can get by with English. The Vatican is a global hub. The priests studying at the North American College speak English. The tourists from Australia speak English. The Philippine nuns—who do a massive amount of the work behind the scenes—often speak English and Tagalog.

Why This Matters for Your Visit
If you're planning to visit, don't panic. You don't need to dust off your high school Latin textbook.
But knowing what language do they speak in the Vatican helps you appreciate the layers of history there. When you see a sign, look at the language used. If it’s a warning sign or a direction, it’s probably Italian. If it’s an inscription on a statue from the 1600s, it’s Latin.
Actually, the inscriptions are a great way to see how the language has stayed exactly the same while the world changed. The Latin carved into the base of the obelisk in the center of the square is the same Latin a Roman centurion would have recognized, even if he’d be baffled by the tourists taking selfies in front of it.
The Misconception of "Vaticanese"
Some people think there is a secret language or a specific dialect. There isn't. But there is "curial" language.
This is more about jargon than a different tongue. It’s a way of speaking that is incredibly formal, indirect, and polite. It’s the language of a bureaucracy that has existed for nearly 2,000 years. They don't say "No." They say "It is not opportune at this time." They don't say "We changed the rules." They say "A new provision has been promulgated."
Whether they are speaking Italian, Latin, or French, that culture of extreme formality—the "Vatican way"—is always there.
Actionable Takeaways for the Curious Traveler
If you want to experience the linguistic diversity of the Vatican firsthand, here is what you should actually do:
- Attend a Wednesday Audience: Pope Francis speaks here. You will hear him give summaries of his speech in dozens of languages—English, German, French, Portuguese, Polish, and Arabic. It’s the best way to hear the "global" Vatican.
- Look at the ATM: Seriously. Go to the one near the post office. Select Latin. It’s a great photo op and a weird reminder that this dead language still has a "home."
- Listen to the Guards: Walk up to a Swiss Guard at the Sant'Anna Gate. If they aren't busy, you’ll hear them switching between German with their colleagues and Italian with the locals.
- Read the Osservatore Romano: This is the Vatican's newspaper. It’s printed in Italian, but they have weekly editions in several other languages. Picking up a copy is a cheap, cool souvenir that shows the linguistic reach of the place.
- Learn basic Italian: If you want to be respectful to the workers, a simple "Buongiorno" or "Grazie" goes much further than a "Salvete." The Vatican is a living museum. Its languages are the layers of paint on the canvas. Latin is the primer, Italian is the main color, and everything else is just the detail work. It’s a mess, but it’s a beautiful, historic mess that somehow works.
Next time someone asks you what they speak there, just tell them: "Everything, but mostly Italian, and officially Latin when they want to sound fancy." That’s the most honest answer you can give.
