It is the winter of 1773, and Boston simmers on the edge of revolution. You have just been sworn into the Sons of Liberty and handed a coded cipher. From the steeple of the Old North Church, through Paul Revere's house and the halls where patriots first dared to speak, follow the hidden trail down to the harbour — and uncover the cause the cipher was protecting before the British close in.
Blending real Revolutionary history — the Boston Massacre, the Old State House, the Tea Party — with a conspiratorial spy mystery, every stop reveals the true story of the landmark while advancing the intrigue. Augmented reality brings the clues to life on the cobblestones and facades, with audio narration in 32 languages. Start whenever you like, go at your own pace, pause for photos. No guide, no fixed schedule, no app to download — just open it on your phone and play. A perfect blend of sightseeing, storytelling and puzzles for explorers, couples and families visiting Boston.
