Imagine living in a 9-story apartment building made of wood and mud bricks. No running water, no toilet, and your landlord is a slumlord who literally doesn't care if the building collapses. 💀 Welcome to the Roman insulae—the OG apartment buildings that housed a million people in downtown Rome.

🏙️ Ancient Skyscrapers & Slums

Rome was the first city to hit a million people, and they had to stack 'em high. The insulae (Latin for "islands") were ancient skyscrapers, some reaching 9 stories tall. The ground floor had shops and businesses, but the upper floors were a whole different story. 😬

  • The higher you lived, the cheaper the rent. Why? Because you were more likely to die. 🔥
  • No running water on the upper floors. You had to haul it up yourself.
  • No toilets. People used chamber pots and just... threw the waste out the window. 🤢
  • Constant risk of fire and collapse. These things were built CHEAP.

Emperor Augustus had to cap the height at 68 feet because they kept falling down. After the Great Fire of Rome in AD 64, Emperor Nero lowered it again to 60 feet. It was a literal death trap.

🤑 The Slumlord Millionaire

One of the richest men in Rome, Marcus Licinius Crassus, owned tons of these insulae. His business model? He allegedly was happy when his buildings collapsed because he could charge higher rents for the new ones. 💀 Talk about a villain origin story.

So next time you complain about your apartment, just remember: at least it probably won't collapse on you. And you (hopefully) have a toilet. 🙏
