Notably, the Marinids were the first to build madrasas in the region. The madrasas of Fes, such as the Bou Inania, al-Attarine, and Sahrij madrasas, as well as the Marinid madrasa of Salé and the other Bou Inania in Meknes, are considered among the greatest architectural works in western Islamic architecture of this period. While mosque architecture largely followed the Almohad model, one noted change was the progressive increase in the size of the "sahn" or courtyard, which was previously a minor element of the floor plan but which eventually, in the subsequent Saadian period, became as large as the main prayer hall and sometimes larger. Notable examples of Marinid mosque architecture are the Grand Mosque of Fes el-Jdid (founded in 1276, one of the earliest Marinid mosques), the expansion of the Great Mosque of Taza in 1294, the Mosque of al-Mansourah near Tlemcen (1303), and the Mosque of Sidi Abu Madyan (1338-39). The Ben Salah Mosque in Marrakesh also dates from the Marinid period, one of the few monuments from this period in the city.
