50 free The Seine trivia questions with answers — geography quiz, new questions added Aug 2026.
This Seine trivia quiz follows the river from its source on the Langres plateau to the sea at Le Havre, with a long stop in Paris. The easy questions ask which country it flows through, which capital it divides into Left and Right Banks, which two natural islands sit in the middle of the city, which cathedral stands on one of them and what the Pont Neuf's name means. From there it moves through the bridges, the boats, the booksellers, the floods and the goddess who gave the river its name. The hard end is for people who have walked the quais more than once: the statue Parisians use to judge flood levels, the bridge Christo wrapped in 1985, the year the Vikings first sailed up to sack Paris, the parapet that collapsed under 45 tonnes of padlocks, the American who tested a steamboat beside the Tuileries, the century-old swimming ban that ended in 2025 and the count of boats in the 2024 Olympic opening ceremony. Every answer was checked against the encyclopaedia entries on the Seine, Source-Seine, Sequana, the Pont Neuf, Pont de l'Alma, Pont des Arts, Pont Alexandre III, the Île de la Cité, Île Saint-Louis, the bouquinistes, the 1910 flood and the 2024 opening ceremony before publishing, and the supporting sentence is stored with each question. Our Paris, France and world rivers quizzes are natural next stops.
