Not all treasure is made of gold. But some of it is.
This trail combines medieval history, urban mystery, and alchemical metaphor in a story that asks what it really means to transform. You’ll follow the seven stages of alchemy — not just as chemical processes, but as a symbolic map of the City of London’s hidden soul.
You’ll start at Tower Hill and pass through places most Londoners have never noticed: secret gardens, lost guilds, ancient hallways, and even medieval public toilets.
It’s part treasure hunt, part fever dream, and entirely grounded in the City’s medieval streets.
You won’t need a guide — the trail is embedded in the stone and shadow.
Fully playable in 11 languages (English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, Arabic) — no guide required.
Starts: Tower Hill Station
Ends: near the Bank of England

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.
