60 free Northern Ireland trivia questions with answers — geography quiz, new questions added Aug 2026.
This Northern Ireland trivia quiz covers the six counties from geology to golf. The easy questions are the ones any visitor should manage: the capital, the shipyard that built the Titanic, the basalt columns on the Antrim coast, the largest lake in the British Isles and the year the country was created. From there it moves into the deeper story, from the Plantation of Ulster and the Siege of Derry to partition, the unionist decades and the Troubles. The harder end is for history buffs and pub-quiz specialists: the Long Committee's six-county plan, Churchill's secret 1940 offer of Irish unity, the 1973 border poll, Bloody Sunday, the Peace People's Nobel Prize, the exact date of the Good Friday Agreement, the first nationalist First Minister, the walls that were never breached, Bushmills' misleading label date, the height of Titanic Belfast and the golfers who won three majors in fourteen months. Language, flags, anthems and murals get their own questions too. Every answer was checked against encyclopaedia entries for Northern Ireland, its cities and its history before publishing, and the supporting sentence is stored with each question.
