The so-called "lambrequin" arch, with a more intricate profile of lobes and points, was also introduced in the Almoravid period, with an early appearance in the funerary section of the Qarawiyyin Mosque dating from the early 12th century. It then became common in subsequent Almohad and Marinid architecture (as well as Nasrid architecture in Spain), often to highlight the arches near the mihrab area of a mosque. This type of arch is also sometimes referred to as a "muqarnas" arch due to its similarities with a "muqarnas" profile and because of its speculated derivation from the use of muqarnas itself. This type of arch was indeed commonly used with "muqarnas" sculpting along the intrados (inside surfaces) of the arch.
