About This Tour
**NEW - AUDIO NARRATION ON ENGLISH LANGUAGE VERSION** Join our quest for the Holy Grail, following a trail of mystic symbols, cryptic sites and secret signs hidden in plain sight. This trail is built on historical fact — if it’s not true it should be! The story it tells takes you way past the point of mere coincidence. What you discover will astonish you. Bring your scepticism to Paternoster Square and take a leap of faith. By the time you reach Covent Garden, you will be convinced! This sacred quest is to be savoured, not raced. It would make an epic pub crawl too! The directions are easy to follow. The clues are visual and rooted in the cityscape. All you need is your phone — and an open mind. Fully playable in 11 languages (English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, Arabic) — no guide required. Starts: Paternoster Square Ends: Covent Garden Distance: 5 km For adults & teens with an interest in history, symbols and storytelling
