A UNESCO World Heritage Site — kids are captivated by the Crown Jewels, armour displays, and resident ravens. Adult tickets ~£34; children (5–15) ~£17; under-5s free. Yeoman Warder (Beefeater) tours are free with admission and highly recommended — engaging storytelling that hooks kids and adults alike.
