What is the Forbidden City?

In the very heart of Beijing sits a city inside a city — a place so grand, so secret, that for five hundred years, almost nobody was allowed to walk through its gates. They called it the Forbidden City, and "forbidden" wasn't just a cool name. If you tried to sneak in without permission, guards would stop you at the door. Probably forever.
The Ming Emperor Yongle built it starting in 1406, and the construction took fourteen years. He wanted a palace that would make everyone who saw it think, "Wow, the emperor must be basically a god." So he hired a million workers — actually a million — to build nearly a thousand buildings, all arranged in perfect symmetry. Every wall, every gate, every courtyard lined up like a giant geometric dream.
