The baserri is a self-sustaining farmstead not located in a village or town. Those who live in a baserri are known as baserritarrak. There is typically a large building made of stone or half-timber, with a sloped roof. The baserri played a large role in Basque culture. In the sixteenth century, each baserri had its own name and legal power. Members of the baserri at this time, even had different clothing to denote whether they were married or unmarried, or male or female . Both men and women helped in the private plots with farming, but generally only women would work indoors during the day, while men would work with the sheep and in the other fields. Overall, the baserri was the center of Basque culture at one point, with some containing cider mills. They were the heart of a family, with some having their own crest. Many Basque surnames also come from locations where baserri were found, such as Isasa, Olaizola, and Aramburu.
