کاخ گلستان( Golestan Palace )
The Golestan Palace (Persian: کاخ گلستان, Kākh-e Golestān), also transliterated as the Gulistan Palace and sometimes translated as the Rose Garden Palace from Persian language, was built in the 16th century, renovated in the 18th century and finally rebuilt in 1865. It is the former official royal Qajar complex in Tehran.
One of the oldest historic monuments in the city of Tehran, and of world heritage status, the Golestan Palace belongs to a group of royal buildings that were once enclosed within the mud-thatched walls of Tehran's arg ("citadel"). It consists of gardens, royal buildings, and collections of Iranian crafts and European presents from the 18th and 19th centuries.
Tehran's arg ("citadel") was built during the reign of Tahmasp I (r. 1524–1576) of the Safavid dynasty (1502–1736), and was later renovated by Karim Khan of the Zand dynasty (r. 1750–1779). Agha Mohammad Khan of the Qajar dynasty (1742–1797) chose Tehran as his capital. The arg became the seat of the Qajars (1794–1925). The court and palace of Golestan became the official residence of the Qajar dynasty. The palace was rebuilt to its current form in 1865 by Haji Ab ol Hasan Mimar Navai.
During the Pahlavi era (1925–1979), the Golestan Palace was used for formal royal receptions, and the Pahlavi dynasty built their own palace (the Niavaran Complex) in Niavaran. The most important ceremonies held in the palace during the Pahlavi era were the coronation of Reza Shah (r. 1925–1941) on the Marble Throne and the coronation of Mohammad Reza Pahlavi (r. 1941 – 1979) in the Museum Hall.
In between 1925 and 1945, a large portion of the buildings of the complex were destroyed on the orders of Reza Shah. He believed that the centuries-old Qajar palace should not hinder the growth of a modern city. In the place of the old buildings, commercial buildings with the modern style of 1950s and 1960s were erected.
