orecast
What lies beneath our feet? Under every street there are pipes, sewers, old walls — and below them layers millions of years old. Werner Wolf, the old wolf with the remarkable nose, takes Kai down and shows what sleeps there.

Six layers, all of them real
🔧 Pipes and cables
Right below the paving: water, power, gas and internet, each tucked neatly into its own trench.
🧱 The sewer
A brick vault where the water of the whole city comes together — with a rat eating cheese.
🏛️ The Roman road
Six to ten metres down, Cologne still holds a paved road from antiquity — with an amphora, a mosaic and a legionary helmet.
⛏️ The mine
Timber beams, an ore cart, a small lamp — and amethyst geodes glowing purple out of the rock.
🐚 The ancient sea
An ammonite sits in the pale limestone. 180 million years ago a warm sea washed over this place, home to ichthyosaurs.
🔥 The deep rock
At the very bottom the rock turns warm, older than anything a child knows. Down here the earth itself is the treasure.
Why this book is different
Real knowledge instead of fantasy gold
Every layer in this book exists. The depths, the finds, the 180 million years — they come from the same open geological data that powers the orecast app.
One important rule
Treasures are looked at, not dug up. The book teaches the rule that real archaeologists live by, without wagging a finger.
Rudy the earthworm
He hides on every underground spread exactly once — with a woolly hat, a Roman helmet, even a snorkel mask.
Questions answered
A closing spread answers what children ask afterwards: how deep are the Romans, why is old stuff always at the bottom, was there really a sea here?

More from the orecast world
The book grew out of orecast — an app that shows what is documented beneath any point in Europe. Same curiosity, same rule: no false precision.
