This mausoleum is located on the western slope of the associated hill, from which one can overlook the ancient town of Chizar. It is very simply designed and has no architectural decoration.

The age of the tombstones and the condition of the mausoleum suggest that it is an older building that was intended to allow the dervishes to stay in seclusion.

The mausoleum is attributed to Ali Akbar, the son of Imam Ali Zayn al-Abedin.

This mausoleum is one of the distinguished buildings of the 14th century and is called Imamzadeh Jafar because Jafar ibn-e Morteza, an important religious figure of that time, is said to have found his final resting place here.

There are two inscriptions on the outer cornice of the octagonal, domed building; it seems as if the roof used to have a pyramid shape, which can no longer be found.

Of the two inscriptions, one is in Kufi style, the other in Tholth style, both resting on fine azure faience tiles. There is also a lettering field in Tholth with white letters on tiles on the entrance portal. As usual, inside the grave building you will find the gravestone, which has an inscription with the names and titles of the. The date on the tape outside the building is 725 AD. (1342 AD), the month of Muharram in the year 725 AD is stated on the tombstone inside.

The well-known and holy tomb of Imam Zadeh Saleh on the edge of the Tajrish bazaar consists of a courtyard with several rooms housing family tombs, an eivan, a portico, a mosque and the domed tomb of Imam Zadeh Saleh. In its current form it dates back to the Qajar period.

An old plane tree in the courtyard and numerous gravestones inside indicate that before the current complex there was an older one, perhaps from the 13th or 14th century, which was gradually rebuilt as it appears today.

Above the entrance door leading to the shrine there are still remains of mud stucco scrolls with azure Nasta'liq script on a white background, in which the names of Fath Ali Shah and Prince Hulagu Khan are mentioned.

The interior of the sanctuary is decorated with beautiful paintings from the Qajar period. The mausoleum has two grave structures: in the larger one, the east, north and west sides are covered with an artistically valuable silver-plated grave structure, while the south side has a wooden grille.

The structure of the second grave consists of square wooden panels.

The silver-plated structure was donated by Mirza Sa'id Khan, a foreign minister of the Qajar dynasty. Above the north portal of the courtyard are two couplets in praise of the Imam Zadeh in white Nasta'liq script on tiles inlaid with azure blue.

In its current form, the Imam Zadeh Saleh is one of the most important religious monuments from the Qajar period, particularly because of the well-proportioned arches of the interior and its method of construction

The Imamzadeh Zayd consists of an inner courtyard, an eivan and a mirror gallery, a tiled dome and other buildings on the sides. It is the tomb of Seyyed Zayd ibn Zain al-Abedin ibn Hussein ibn Ali. The earliest dating of the mausoleum can be found on the grave, where the month of Rajab is 920 AD. is held. The same date can also be found in a bas-relief with Naskh script above the grave.

This corresponds to the year 1514 AD, which is why the basic structure of the mausoleum can be dated to the beginning of the 16th century.

In the tomb and above the inlaid door that leads from the Eivan to the Haram, the following dates can be seen: 1297 and 1309 AD. (1879 and 1891 AD). These two years mark the end of the renovation work on two inscriptions on tiles on the building, which can be dated to the end of the 19th century AD.

Near the mausoleum there is a hall of mirrors where some former dignitaries are buried.

Under the Eivan, near the mausoleum, there is a marble tombstone, the grave of the brave Zand prince Lotf Ali Khan, who also found his final resting place in the Imamzadeh Zayd in Tehran.

The tile work on the dome, the renovation of the Eivan, the reflections on the gallery and in the interior of the sanctuary and on the tomb all date back to the beginning of the 20th century.
