Step inside the last great monument of the Mughal Empire — and discover everything most visitors miss. Enter through the Roshnai Gate, walk the Hazuri Bagh past Allama Iqbal's tomb, and climb the twenty-two steps into a mosque that held the world's record for three hundred and five years. Twelve guided stops carry you through hidden chambers, painted ceilings, four leaning minarets, and twenty-four corridors that once held eighty students. Each stop is an interactive puzzle, an AR scan, or a story you collect. Six letters lead to a final vault. Three coupons from local cafés, heritage walks, and the Lahore Fort wait in your wallet. Roughly 60–90 minutes. Best at golden hour.
