Golestan Palace, a UNESCO World Heritage Site, is in Tehran, Iran.
The palace is a historic royal complex in the centre of Tehran, within the area once enclosed by the city’s old citadel walls. It became the official seat of the Qajar dynasty after Agha Mohammad Khan chose Tehran as his capital in the late 18th century. Much of the complex’s surviving appearance dates from the 19th century.
Golestan is not a single palace building but a group of royal structures surrounding gardens, pools, and courtyards. Its halls combine Persian decorative traditions with European-influenced design, including elaborate tilework, mirrored interiors, paintings, and imported gifts. The complex later hosted important ceremonies under the Pahlavi dynasty.
UNESCO added Golestan Palace to the World Heritage List in 2013 under cultural criteria recognising its artistic and architectural importance. The name can cause confusion because Golestan is also the name of an Iranian province, but this palace is specifically located in Tehran. It should not be confused with Sa’dabad or Niavaran, other major palace complexes in the capital.
