It is not known exactly when this garden was built. But we do know that this garden existed in the Seljuk era in the 12th century. In 1983, Nasir ol-molk had a small palace built by the architect Mohammad Hasan, who had already built the Nasir ol-molk mosque in the historic center. Architects in the Qajar era decorated this building with beautiful ceramics and plaster.

The name of Eram (or Iram) alludes to a paradisiacal garden created by a ruler of pre-Islamic Arabia, and which has become, in Persian literature, an archetype of beauty.
