Yes, San Marino is a country, and here's why it isn't Italy

It’s the most searched question about San Marino, and I can see why. You arrive on an Italian bus from an Italian station, people speak Italian, you pay in euros and nobody stops you at the border. Everything points to an Italian hill town with a nice name. It isn’t one, and the difference shows up in things that affect your trip more than you’d expect.

Yes, San Marino is a country

San Marino is a sovereign republic. It has its own parliament, the Great and General Council, with 60 members elected by universal suffrage, its own government and two heads of state who change every six months, the Captains Regent. It joined the UN in 1992 and the Council of Europe in 1988, issues its own stamps and coins, and keeps its own diplomatic missions abroad.

There’s one detail I think proves it better than anything. The United States didn’t recognise San Marino with a treaty but with a letter. In 1861 the Captains Regent offered Abraham Lincoln honorary citizenship, he accepted, and according to the State Department that reply was how the US recognised the republic. I tell the story in San Marino facts.

Where is San Marino?

In north-east Italy, inland from the Adriatic. It’s an enclave, a country entirely inside another. Rimini province borders it on three sides and Pesaro and Urbino closes the southern edge. The capital sits on the ridge of Mount Titano, 27 km from Rimini airport, and the country runs down from there to Dogana, where the road from Rimini comes in. Where each piece falls is on my map of San Marino.

Is San Marino part of Italy?

No. Italy surrounds it but doesn’t govern it. The relationship is close, and that’s where the confusion starts. San Marino’s government talks of a centuries-old absence of border controls with Italy, so you simply drive in. Because the only way in is through Italy, Schengen rules apply, and the foreign ministry says visitors from outside Schengen need whatever lets them enter and cross it. For a British passport holder, that means Italy’s rules. According to Wikipedia, a friendship treaty with Italy signed in 1862, revised in 1939 and 1971, guarantees its independence.

Capital, population and language

The capital is the City of San Marino, on top of Titano, which the government describes as home to the state’s main monuments. It has 4,158 residents and isn’t the biggest place. The most populous castello is Serravalle, with 11,243, and within it lies Dogana.

In all, 34,167 people lived in San Marino at 30 June 2026, 29 more than a year earlier. Of those, 28,165 are Sammarinese citizens, 5,199 Italian and 803 other nationalities. What strikes me is the other side of the ledger. 18,047 Sammarinese live abroad, mainly in Italy, Argentina, the United States and France, which is more than half the number at home.

People speak Italian, and the local variant of Romagnol too. Spain’s foreign ministry lists Italian as the official language and Sammarinese as unofficial, and I go into both, with a few useful phrases, in what language is spoken in San Marino.

Is San Marino in the EU?

No, and it’s worth being clear. Its foreign ministry says San Marino isn’t part of the EU and is legally a third country. It has had diplomatic relations with the EU since 1983, a customs union in force since 2002 and a 2012 monetary agreement letting it use the euro and mint its own national side. The practical detail is in money in San Marino.

The consequence you’ll feel most is on your phone. EU roam like at home covers member states, Iceland, Liechtenstein, Norway, Moldova and Ukraine, and San Marino isn’t on the list. For UK visitors, whose networks have set their own European charges since Brexit, it’s one more place to check. I go through it in roaming in San Marino.

Why does San Marino exist?

By tradition, since the year 301, when a Dalmatian stonemason called Marinus sought refuge on Titano. But the answer that convinces me is a different one. San Marino has had written institutions since 1243, settled in 1463 on the territory it still holds and never asked for more. When a united Italy was born, it signed a friendship treaty with it rather than joining.

Mountain, size and caution, that’s my explanation. A crag that was hard to take, a country too small to trouble anyone, and rulers who, whenever they had the chance to grow, chose to stay as they were. I set it out with dates, from Napoleon to Garibaldi and wartime neutrality, in the history of San Marino. To plan the trip with all that in mind, start with my San Marino travel guide.
