Spartan houses were simple farming homes. They could be built over 2 storeys and still have a central courtyard, but were very basic humble homes with no adornments. Like many homes in Ancient Greece they were painted white to reflect the heat.
The farms in Sparta were managed by the women, as the men lived in barracks; therefore women held the dominant role in Spartan life.
Although Sparta was a city-state, it was really a collection of villages surrounded by mountains. This gave it natural protection from invaders.
