Press the big red “START” button on your time machine, hold onto your hat, and *whoosh*—you’ve just landed in the middle of the busiest, loudest, most amazing city on Earth in the year 1 CE. The first thing you notice is the smell: a mix of warm, crusty bread baking in stone ovens, sweet honey and roasted nuts from street food stalls, a little bit of wet horse manure from the thousands of horses pulling carts, and the sharp, salty tang of the Tiber River just a few blocks away.

You look up and see rows and rows of red brick apartment buildings, some as tall as 5 or 6 stories (that’s higher than most houses in your town, right?). Above the rooftops, you spot a huge, gleaming white building with a giant dome—this is the Pantheon, a temple built for all the Roman gods, and it’s so well built that it’s still standing today, almost 2,000 years later. A little further away, you hear a deafening roar of cheers—that’s the Colosseum, where gladiators fight and animal shows happen, and it’s so big it can hold 50,000 people, more than most big football stadiums now.

Wait a second—公元1年的时候，中国是汉朝哦！汉朝的皇帝是汉平帝，那时候的中国和罗马是地球上最厉害的两个超级大国，就像现在的两个大国一样，不过它们离得特别远，中间有沙漠和高山，所以从来没有见过面，是不是很可惜？

Welcome to the Biggest City on Earth in 1 CE!

Right now, Rome is the largest city in the entire world, with more than 1 million people living inside its walls. To put that in perspective: that’s bigger than most modern cities you know, like Portland, Oregon, or Nashville, Tennessee! The next biggest city at the time is Alexandria in Egypt, with only about 500,000 people—half the size of Rome. Even 1,000 years later, in the Middle Ages, no European city would be as big as Rome is right now. It’s like the New York City or Tokyo of the ancient world.

Why Is Rome Built on Hills?

Rome isn’t built on flat ground—it’s built on seven big hills, which is why it’s called the “City of Seven Hills.” Do you know why the Romans chose to build on hills? Because the Tiber River floods a lot in the spring, when the snow from the mountains melts. If they built on flat ground near the river, their houses would get washed away! Building on hills keeps them safe from floods, and it’s also easier to defend against enemies—if someone attacks, you can just roll big rocks down the hill at them.

The fanciest neighborhoods are on the highest hills, like the Palatine Hill, where the emperor and the richest families live. The poorest people live in the low valleys between the hills, near the Tiber River, where floods are most common and the air is full of smoke from all the cooking fires.

Rome is also super organized. The city is split into 14 districts, each with its own market, bakeries, and small temples. The main public spaces are the Roman Forum, which is like the city’s main square and government center, where people go to shop, listen to speeches, and watch parades. There are also over 200 public fountains, so you can get fresh cold water anywhere in the city for free—no plastic water bottles needed! The Romans built amazing underground pipes called aqueducts to bring fresh water from mountains 50 miles away, and their drainage system is so good that most streets don’t have puddles even when it rains hard.

<digital-only> <details> <summary>💡 Fun Fact: Roman Roads</summary> You’ve probably heard the saying “All roads lead to Rome.” That’s true! The Romans built over 250,000 miles of roads across their empire, all paved with stone, with sidewalks and drainage ditches on the sides. Many of these roads are still used today, 2,000 years later. The roads are built with a slight curve in the middle so rainwater runs off into the ditches, so they never get muddy. </details> </digital-only>

What Do They Speak? Latin, of Course!

The official language of Rome is Latin (say it: *LAT-in*). It’s a really old language that no one speaks as a first language anymore, but it’s the grandparent of a lot of languages we know now, like Spanish, French, Italian, Portuguese, and even Romanian! You might even know some Latin words already, because hundreds of English words come from Latin. Let’s play a little game: which of these words do you think come from Latin? 1. Gladiator 2. Pizza 3. Exit 4. Calendar 5. Panda

If you guessed all of them, you’re right! Here’s why:

• *Gladiator* comes from the Latin word *gladius*, which means “sword,” because gladiators fight with swords.
• *Pizza* comes from the Latin word *pinsere*, which means “to press flat,” because pizza dough is pressed flat.
• *Exit* comes from the Latin verb *exire*, which means “to go out.” That’s why exit signs in movie theaters and schools
