Fuerteventura's windmills are identifiable by gender. Female windmills (moilinas) are one storey high rectangular buildings, while male windmills (moilinos) are 2 or 3 stories and circular.
Molinos date from mid to late 1700s, they were round and built out of stone and wood and whitewashed with lime. The miller's tools were stored on the ground floor, the grain on the second and the milling machinery on the top floor.
Most moilinos and moilinas have four sails although there are some with six or even twelve.
