Alchemy Trail is a symbolic journey through medieval London, following the seven stages of transformation in the alchemist’s art — from calcination to coagulation. As you walk the winding alleys of the old City, you’ll follow a trail that leads you to the Philosopher’s Stone and the secret location of Dick Whittington’s buried gold. Clues are embedded in the city itself — coats of arms, carvings, architectural details, and epigraphs. You’ll unlock verses, codes, and fragments of a buried past, one stage at a time. The route is 4km and fully step-free. Fully playable in 11 languages (English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, Arabic) — no guide required.
