Much of the focus of the complex is given to the east
iwan, a rectangular interior space with one un-walled side. The facade consists of three entrances from the large polygonal bay, covered in intricate mosaics. Despite the grandeur of the ornamentation, the
iwan walls are rough. This is likely due to the rushed nature of construction, which only took around three years despite the fact that decoration itself is usually completed in the same length of time, suggesting that Qavam al-Din designed the ornamentation himself, which was then executed by a team of
mosaicists. An outdoor facade extends down a north and a south facing facade which also possess entrance portals, albeit, smaller and less impressive. The north facing facade leads to a
masjid, and the south facing facade leads to the
Jamaat Khana. The facade is lit by a window in each of four recesses on each side. A white marble ledge projects from the lower portion of the brickwork. The walls here are vibrantly colored. The banai brickwork style is employed again. The arches are decorated with
bisque tiles, mosaic
faience. The
dado is formed of marble mosaic. The
dihliz appears octagonal due to the painted dado which hides the bottom of the arches. Paintings of trees reach from the dado to the ceiling. Each wall has a door: the north to the
masjid, the south to the
Jamaat Khana, and the east west to the courtyard. The east facing doorway is pointed and the other three are segmented, but they all appear rectangular due to
tympanums. The north, south, and west tympanums are painted according to a calligraphic and floral scheme. Scenes of Madinah, Mecca, and, puzzlingly, palaces, kiosks and trays of food are painted above the arches. The masjid, or mosque, is divided into five sections by arches. Six alcoves, on either side of the middle three sections, open up to the entrance facade on the west and the courtyard on the east. The north and south sections are in the form of bays, and allow five means of entry between them. A staircase in the south bay leads to an
ambulatory. Plaster
muqarnas cover the ceiling and alcoves. The dado is composed of buff hexagonal tiles and blue and black mosaic faience, broken up by narrow borders of four pointed stars. The
mihrab is a simple inscribed marble slate. The
Jamaat Khana is distinguished from the masjid in only a few ways: it lacks a mihrab and a tiled dado. The second story is composed of a room and the two galleries that lead to it from the staircase of either of the masjid or the
Jamaat Khana. Its windows face over the entrance facade and the courtyard. The courtyard is enclosed on the north and south by two long facades. The south facade has more damage than the rest of the building. Extensive restoration has made it difficult to predict what it would have looked like when built. However, the southern
iwan is similar to the north. It has been very well preserved despite the damage sustained by the rest of the south facade. Due to its bigger size, a relieving arch [link to discharging arch] was built in to support the brickwork. Four rooms extend one by one to complete the facade. The north facade is similar to the south facade. However, five rooms have been added.
The Zarnigar-Khanah and the Namakdan The Zarnigar Khanah is two hundred meters from the shrine. The entrance portal faces north and is covered by two semi-domes. A large dome span of covers the central hall. A niched mihrab is present on the west wall, and the other four walls have a door. A window over each door and the mihrab is framed by
squinch arches. The pavilion, primarily known as the Namakdan, is
dodecagonal on its outside and octagonal inside. Four eyvans open the outside of the structure toward four more small octagonal chambers, which further open to the central pavilion. Recently, the vault was split into a first and second story. == Architecture ==
