The building follows some of the typical design elements of oasis architecture in the predominantly Berber regions of southern Morocco: it is made from rammed earth or mudbrick and has square corner towers with geometric decoration.[7][8] The original ksar (village) corresponded to the walled enclosure still occupying the northern section of the site, but it is ruined today. The Kasbah itself (or tighremt), a large late 19th-century mansion for the Nasiri family and (historically) their servants, occupies the rest of the site, stretching towards the south along the river. Although it has various courtyards and elements, the most imposing structure is the main house, an almost square building with four corner towers (though a fifth tower has since been added on the south side of the structure).[3] A garden has been added to the courtyard in the southern section of the kasbah, although this is a design element imported from Marrakesh during recent restorations.[4][5]
