Until the 1920s, Tajrish and neighboring Shemiranat were a collection of small villages along Capital’s border. The area was relatively disconnected from Capital’s urban with the exception of Old Shemiran Road, currently known as Shariati Avenue. With the construction of Pahlavi Road (now named Valiasr Street) in 1930s and Modarres Highway, then known as Shahanshahi Boulevard, the Northern suburbs became highly accessible from downtown and rapid extension became possible.Popular tourist spots in Tajrish are the old bazaar and a mausoleum called Imam Zadeh Saleh.
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.
