Layout The madrasa's floor plan occupies a nearly square space measuring approximately 40 by 43 meters. Like many Islamic buildings, the courtyard is itself centered around a large, shallow reflective pool, measuring approximately 3 by 7 meters. In particular, the decorative arrangement follows the architectural traditions established in earlier Marinid madrasas:
zellij tiling is used along lower walls, calligraphic friezes are generally present at eye-level, and the middle and upper areas of the walls are covered in stucco decoration before transitioning into wooden elements, including ornately carved
eaves. The arches of the ground-floor galleries in the courtyard also have stucco
consoles supporting carved wooden
lintels that bridge the distances between each pier. The main central courtyard of the madrasa communicates a strong visual experience for visitors and students via these embellishing elements and their symmetrical arrangement. This courtyard is entered from the vestibule via a wooden screen (
mashrabiyya) under a monumental archway which is itself decorated with carved stucco. Although the student cells that surround the courtyard have little to no interior decorative elements, the small secondary courtyards that grant access to them do bear some stucco and wooden decoration. The motifs carved into wood and stucco include traditional elements such as
arabesques,
sebka (or
dark wa ktaf),
calligraphic inscriptions, and
muqarnas, as well as more distinctly Saadian-era motifs such as
pine cones. The street entrance of the madrasa is overlooked by an elaborate
muqarnas (stalactite or honeycomb-like sculpting) vault in front of the doorway, while another
muqarnas cupola is found in the ablutions chamber. The doors of the madrasa are plated with
bronze forming an interlacing
geometric pattern and enhanced with shallow carved arabesque motifs. The cedar wood lintel above the doors is carved with an Arabic inscription on an arabesque background. The inscription names and praises Sultan Abdallah as the builder of the madrasa. Numerous other inscriptions are also found throughout the building on various surfaces, often consisting of Qur'anic
verses. The large
Kufic inscription around the arch of the
mihrab, for example, includes the
basmala and the
tasliyya followed by verse 36 and the beginning of verse 37 from the
Surah an-Nur. File:Madrasa ben Yusuf Marrakech 10.jpg|The
