Medieval Moroccan mosques also frequently followed the "T-type" model established in the Almohad period. In this model the aisle or "nave" between the arches running towards the mihrab (and perpendicular to the qibla wall) was wider than the others, as was also the aisle directly in front of and along the qibla wall (running parallel to the qibla wall); thus forming a "T"-shaped space in the floor plan of the mosque which was often accentuated by greater decoration (e.g. more elaborate arch shapes around it or decorative cupola ceilings at each end of the "T").
