A ghorfa ( room) is a vaulted room used by Berbers for storing grain. They are often stacked as multistory structures, sometimes reaching four stories high. Traditionally, the rooms were grouped together as a ksar, a fortification used by Berber villages in the Maghreb to store large amounts of grain. Ghorfas were featured prominently in the film Star Wars: Episode I – The Phantom Menace as the slave quarters of Mos Espa, home to Anakin Skywalker. These scenes in the film show ghorfas from several locations in southern Tunisia, including Ksar Ouled Soltane and Ksar Hadada. Ghorfa in Malta could also be a lonely room in a field, a bedroom, any kind of storage room, animal shelter and other functional traditional rooms.
