Rome's Stacked Homes: Rent, Stairs, and Daily Life

Most people think of Roman life as marble villas and fancy banquets. That lifestyle belonged to the richest few. The average person lived in an insula. These were apartment blocks that filled entire city blocks. By late antiquity, Rome had more than forty-four thousand insulae. There were fewer than two thousand private houses. As many as one million ordinary Romans called these buildings home by the second century CE.

An insula stood like an island with streets flowing around it. Shops opened on the ground floor. Renters lived above. Stairs led up to each flat. The higher the floor, the cheaper and worse the place became. Before elevators, climbing was tiring and risky. Rich families stayed on the lower levels. Poor families climbed toward the roof. Most tenants lived in one tiny room called a cella. Whole families shared that cramped space. Smoke drifted up from cooking fires below. Chamber pots were emptied from windows above. Walls cracked. Landlords told everyone that nothing was wrong.

Not every insula was a slum. Some buildings in the port city of Ostia were large and bright. They had courtyards and several rooms. Some even featured mosaics and fancy reception areas. So an insula could be a fancy home or a run-down tenement. Rome had both kinds. The Latin word insula means island. That name made sense because water-like streets surrounded these buildings.

Rome kept growing because people moved there for work, food, and power. The city handed out free grain starting with Emperor Augustus. That pulled in even more migrants. Europe would not see a city that large again until London in the nineteenth century. Rome had no steel frames, no elevators, and no modern plumbing. Builders relied on concrete made from lime and volcanic ash. The ash came from Puteoli and the Bay of Naples. When it touched water, it turned to stone. The Roman writer Vitruvius said the city had to build higher because so many people needed places to live.

A former slave named Ancarenus Nothus left a tombstone outside the city. His words sound like a dark joke about rent. He said his body no longer felt hunger. He no longer paid a deposit on rent. Instead, he enjoyed free lodging forever. It was a funny way to describe a hard life. Yet it feels familiar to anyone paying rent in a crowded city today.
