The Negarestan Palace or Garden was built between 1843-1849 by the order of Fathali Shah Qajar, with the aim of creating a government summer center outside Tehran city. Due to the presence of numerous paintings and drawings of Fathali Shah and his courtiers in various buildings, this Garden became known as Negarestan.

This garden palace was very large in its early days. So that according to the Qajari documents, its southern gate was located on the northern side of Baharestan Square, and from east it was leading to Shemiran Gate and from the west to Safi Alishah Street.

But it should be acknowledged that Negarestan Garden has been exposed to many destructions and only 11,469 square meters of it remains and it is owned by Tehran University. Magnificent mansions and halls such as Delgosha mansion, Salam Hall, Qalamdan Hall and several reservoirs were built in this garden palace.
