In the 13th century, a tomb was built for Saadi by Shams al-Din Juvayni, the vizir of Abaqa Khan.

During the reign of Karim Khan Zand, a mausoleum of two floors of brick and plaster, flanked by two rooms, was built.

[1] The current building was constructed between 1950 and 1952[2] to a design by the architect Mohsen Foroughi and is inspired by the Chehel Sotoun with a fusion of old and new architectural elements.

The building of the tomb of Saadi Shirazi has a cubic shape from the outside, but from the inside, it is in the form of an octagon with walls of marble and an azure arch.

10 meters below the tomb of Saadi Shirazi, there is an aqueduct whose water contains sulphurous material and also quicksilver.
