The Sa'dabad Complex is a 300 hectare complex built by the Qajar and Pahlavi monarchs, located in Shemiran, Greater Tehran, Iran. Today, the official residence of the President of Iran is located adjacent to the complex. The complex includes more than 180 hectares of natural forest, streets, qanats, galleries, and museums. The complex was first built and inhabited by Qajar monarchs in the 19th century. After an expansion of the compounds, Reza Shah of the Pahlavi Dynasty lived there in the 1920s, and his son, Mohammad Reza Pahlavi, moved there in the 1970s. After the 1979 Revolution, the complex became a museum.
