Ancient Rome had apartment buildings up to 10 storeys tall
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
Ancient Romans lived in multi-storey apartment buildings called insulae — some reaching 8–10 storeys. Rome may have had over a million inhabitants at its peak, making it the largest city in the ancient Western world, and most people lived in these dense rental apartments rather than individual houses. The ground floor was typically occupied by shops; upper floors housed increasingly poor tenants. The buildings were poorly built and prone to collapse and fire — Augustus Caesar famously passed a law limiting new insulae to 70 feet (21 metres) after too many collapsed.
Urban apartment living feels like a modern phenomenon. Discovering that 2,000-year-old Romans experienced the same density, the same landlord relationships, and the same housing-quality anxiety as modern city-dwellers collapses the distance between ancient and contemporary life.
