Roman Houses Had Tiny Windows
Step into a grand Roman villa and you might squint—most rooms sat in semi-darkness, lit by windows no bigger than a loaf of bread.

Tiny Windows, Big Reasons
Even in luxury, Romans designed their houses with tiny, high-set windows—sometimes just slits—mainly to keep out thieves and the burning Mediterranean sun. Only a few rooms, like the atrium or triclinium, got much natural light. Interior spaces relied on oil lamps, their smoke leaving stains that archaeologists still trace along ancient ceilings.
