50 free London trivia questions with answers — geography quiz, new questions added Aug 2026.
London has been a major settlement for nearly 2,000 years, from the Roman trading post of Londinium to a city of more than nine million people spread across 32 boroughs and the ancient square mile of the City. It has burned down, been bombed, hosted three Olympic Games and built the world's first underground railway, and it still runs on a street plan that survived the Great Fire of 1666. These 50 questions roam the whole city: Boudica and Alfred, the plague and the fire, the Tube map and the Elizabeth line, Big Ben and Tower Bridge, the Shard and the London Eye, the Royal Parks, the museums of Albertopolis, the airports, the accents and the chocolate digestive factory in Harlesden. Easier questions cover the landmarks every visitor knows; harder ones ask which borough holds City Hall, which bank holiday hosts the Notting Hill Carnival, and which EMI engineer invented stereo sound in 1931. Every answer is cited to a page we checked, with a short explanation so you learn something even when you miss. Play it solo, or print it for a pub quiz.
