Insulae, Ancient Slums
Housing in Ancient Rome
Overview of Population and Housing
- At its peak during the 3rd Century AD, Rome had an estimated population of over a million people, despite being only about 8 square miles in size.
- To accommodate this large population, many apartment blocks known as insuli were constructed. These buildings were several stories tall and made from flammable materials such as wood, mud brick, and concrete.
- Each insula could contain up to six or seven apartments referred to as kakula, indicating the cramped living conditions for the poorer citizens.
Etymology and Structure of Insuli
- The term insula comes from Latin meaning "island," which reflects how these apartment buildings were often isolated structures with clear spaces between them.
- The prevalence of insuli indicates that there were likely around 15,000 or more such buildings in Rome, primarily serving as housing for the poor.
