The Sa'd al-Saltaneh Caravanserai is designed on a massive square plan, reflecting the classic Iranian architectural style. The structure features four iwans (rectangular halls, walled on three sides, with one side open) that face a central courtyard. To enhance the aesthetic appeal, the interiors are adorned with Muqarnas, which are ornate, honeycomb-like vaulted decorations common in Islamic architecture.

The facility was designed for practical utility and luxury. The Hujrehs, or traveler rooms, are strategically positioned one meter above the courtyard ground level. A central feature of the complex is the Hashti (an entrance vestibule) located behind the southern iwan, which houses the largest gonbad (dome) in the structure, supported by four adjacent semi-domes.

The Grand Halls and Connectivity

The caravanserai is organized around two primary axes that intersect at the Hashti. The east-west axis is known as Dalan-e Qeisariyeh (Caesar's Hall), which serves as a vital link connecting the caravanserai to the city's "Bazaar of Vizir." The north-south axis is named Dalan-e Ghahremani (Ghahremani Hall). In addition to the main central area, the complex includes two smaller courtyards located to the east and west.
