50 free Monaco trivia questions with answers — geography quiz, new questions added Aug 2026.
Monaco is two square kilometres of the French Riviera that has been ruled by the same family since a Grimaldi disguised as a monk seized its fortress in 1297. It is the second-smallest country on Earth, the most densely populated, and home to more millionaires per head than anywhere else, and it has not charged its citizens income tax since 1869. This quiz covers the whole principality: the Rock of Monaco-Ville, Monte Carlo and its 1858 casino, the Franco-Monégasque treaties, the 1910 revolution, the wartime occupation, Rainier III's 56-year reign and Prince Albert II's bobsleigh career. It also takes in the things everyone knows Monaco for: the Grand Prix run through the streets since 1929, Ayrton Senna's six wins, Grace Kelly's Oscar and her 1956 wedding, AS Monaco's eight French titles despite not being French, the Oceanographic Museum that Jacques Cousteau ran, the Café de Paris, and the red-and-white flag that is nearly identical to Indonesia's. Easy questions ask which country surrounds Monaco; hard ones want the price France paid for Menton and Roquebrune and the year Italian stopped being the official language. Every answer was checked against Wikipedia's articles on Monaco, the Grand Prix, Grace Kelly, the flag, AS Monaco, Prince Albert II and the Oceanographic Museum, and each question carries the sentence that supports it.
