Okay kiddo, have you ever seen a secret tunnel in a movie or a cartoon? Fogou is a real-life secret tunnel that was built a long, long time ago in a place called Cornwall in England.
Fogou is a special kind of tunnel made out of stones that were carefully placed on top of each other to make a long and narrow passageway underground. It's kind of like a big puzzle made out of rocks.
Now, why would anyone want to build a tunnel underground? Back then, people didn't have many comfortable homes like we do today. Fogou was built to keep people safe from the cold weather and any scary enemies that might come their way.
Fogou is also special because it's very dark inside - so dark that it's hard to see anything with your eyes! But don't worry, there are special flashlights that you can use to see inside.
Exploring Fogou is like going on a big adventure! You have to crawl and walk through the tunnel, and it gets really spooky and mysterious inside. But don't worry, you're not alone - there will be other people there to show you around and make sure you're safe.
So, that's what Fogou is all about - a special tunnel underground that was built a long time ago to help people stay safe and warm.
