Abdullah-khan Madrassah (1588-1590)
Architecturally, Abdullah-khan Madrassah is more complex than Madrassah of Modari-khan. The entrance hall forms a gallery with two passages to the court yard. Mosque and classrooms (darskhana) are located in the gallery.
The mosque is located at angle with major building. It was done to focus a praying niche (mihrab) right to Mecca. The inner courtyard has four aivans with high portals.
Majolica was used instead of polychromic mosaic for facing. Geometrical patterns of five, eight and nine-point stars originally decorated the dome.
