Golestan Palace

The Golestan Palace, 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 a UNESCO World Heritage Site, the Golestan Palace belongs to a group of royal buildings that were once enclosed within the mud-thatched walls of Tehran's arg. It consists of gardens, royal buildings, and collections of Iranian crafts and European presents from the 18th and 19th centuries.
