Monaco is a sovereign country smaller than New York's Central Park, squeezed between the mountains and the sea on the French Riviera. Into about two square kilometres it fits a palace on a rock, a 19th-century casino, a Formula 1 circuit through its streets and whole districts built on land taken from the sea. Here are the facts and stories behind it.
10 fun facts about Monaco
- The world's second-smallest country: only Vatican City is smaller. Monaco covers roughly two square kilometres, which makes it one of the most densely populated countries on earth.
- A minority at home: the 2024 census counted 38,423 residents, but only 9,262 of them held Monégasque nationality, about one in four.
- Armed monks: the princely coat of arms is held by two monks carrying swords, a nod to the disguise that won the Grimaldis the Rock in 1297 (see the legend below).
- Citizens may not gamble: Monégasques are not allowed into the gaming rooms of the Casino de Monte-Carlo. The casino company was founded in 1863, and the building's grand façade and opera hall are the work of Charles Garnier, architect of the Paris Opera.
- Named after a prince: the headland opposite the Rock was called Les Spélugues until 1866, when it was renamed Monte-Carlo, 'Mount Charles', in honour of Prince Charles III.
- A Grand Prix since 1929: the first Monaco Grand Prix was held in April 1929. The race still runs through the streets, past the casino and through the tunnel under the Fairmont hotel.
- A museum built into a cliff: the Oceanographic Museum, founded by Prince Albert I and inaugurated in 1910, rises straight out of the rock face above the sea. Jacques-Yves Cousteau was its director from 1957 to 1988.
- A country that keeps growing: much of Fontvieille stands on about 22 hectares reclaimed from the sea from the 1960s onwards, and in December 2024 Prince Albert II inaugurated Mareterra, a new six-hectare district built on the water next to Larvotto.
- A Hollywood princess: the actress Grace Kelly married Prince Rainier III in 1956. Both are buried in St Nicholas Cathedral on the Rock, begun in 1875 on the site of an older parish church.
- Euro, but not EU: Monaco is not a member of the European Union, yet it uses the euro and mints its own euro coins.
The legend of François the Cunning
In the 13th century, Genoa was torn between two factions, the Guelphs and the Ghibellines, and the Grimaldis, a Guelph family, had been driven out of the city. On the night of 8 January 1297, the story goes, a Franciscan friar knocked at the gate of the Ghibelline fortress on the Rock of Monaco and asked for shelter. Once the gate was opened he drew a sword from under his habit, and his men stormed in behind him. The friar was François Grimaldi, remembered as Malizia, 'the cunning'. He held the fortress for only a few years, and the family lost and regained the Rock several times before their rule became permanent in the 15th century.
Monaco-Ville, the Rock, explained
Monaco-Ville is the old town on the rocky headland that juts into the sea, and it is where Monaco began. Its narrow lanes hold the Prince's Palace, St Nicholas Cathedral, the Oceanographic Museum and small squares with views over both harbours. Every day just before noon the Carabiniers of the Prince change the guard in the palace square, a ceremony that in its present form dates back to the early 19th century. Look up at the street signs: many are written in French and in Monégasque, the local dialect, which children still learn at school.
What to eat in Monaco
- Barbajuans: small fried pastry parcels filled with Swiss chard, ricotta and parmesan, Monaco's signature snack and a fixture around National Day on 19 November.
- Socca: a thin chickpea pancake baked in a very hot oven, shared with neighbouring Nice. Eat it hot, with plenty of black pepper.
- Stocafi: dried stockfish slowly stewed with tomatoes, olives and white wine, a traditional Monégasque dish.
- Fougasse monégasque: a sweet flat bread flavoured with orange blossom and topped with almonds and red and white aniseed sprinkles, the colours of the national flag.
Good to know before you go
- Monaco is steep. Public lifts and escalators link the harbour to the upper streets and to the Rock, and they save a lot of climbing.
- The Formula 1 Grand Prix takes over the streets in late spring. Grandstands go up weeks in advance and some roads and pavements change, so check the dates if you prefer a quieter visit.
- Monaco-Monte-Carlo station is built inside the mountain, and trains run along the coast to Nice and Menton. The perched village of Èze is an easy half-day trip.
