CASATA

casata (k-say-tuh). Hist. A house with enough land to support one family.

• In medieval Italy, a casata typically consisted of a small house and a plot of land for farming.
• During the Renaissance, wealthy families in Florence built grand casatas with extensive gardens and orchards.

These examples illustrate how a casata was a self-sufficient dwelling for a single family, providing both shelter and sustenance through farming or gardening. The size and grandeur of a casata could vary depending on the wealth and status of the family who owned it.
