A thousand years ago, the name of Tajrish was written as Tajrasht, which was one of the urban villages. As Najmuddin Ravandi has mentioned in his description of the reign of Tughrel Seljuqi, Then the Sultan went from Tabriz to Shahreri to be married to Dar al-Mulk. A little bit of suffering came over him, he went down to the outer palaces, to the door of the Diyeh (village) of Tajrish, because of the coolness of the air, how hot the air was (to the year 455 AH). Interestingly, Tughrel died in the same Tajrish and his body was moved to Shahreri for burial. Of course, the blessed tomb of Saleh Ibn Musa Kazem, the brother of the 8th Imam of Shiites, is another proof of the antiquity of this area.
When he hears the news of his brother’s coronation, he leaves Iraq for Homeland. It seems that a person named Hasan Behbahani was chasing Imamzadeh in Karkh Bridge, which is Karaj today, and he martyred him in Golshan Garden of Tajrish village next to the same old plane tree. The people of this area built a dome and court for him in respect of his appointment as an imam. There is information about other areas of Shemiran from the distant past. But there is still no more information about Tajik. Tajrish is at the foot of the Alborz mountain range and Tajrish field is located at an altitude of 1600 meters above sea level.
