Chehel Sotoun is a majestic pavilion in the middle of a Persian garden and it is one of the best combinations of Safavid architecture and art.
The garden itself is a UNESCO world heritage site and one of the finest examples of Persian horticulture.
Construction of the palace was ordered by Shah Abbas II. He and his successors held their official meetings and receive dignitaries and ambassadors, either on the terrace or in one of the stately reception halls.
The name, meaning "Forty Columns" in Persian, was inspired by the twenty slender wooden columns supporting the entrance pavilion, which, when reflected in the waters of the fountain, are said to appear to be forty.
The paintings and artwork inside the palace are extremely valuable and incredibly beautiful. They describe the important wars and victory of Ottoman Turks
over the Iranians and the glorious victory of Nader shah in the battle of Karnal.
