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 palace has many frescoes and paintings on ceramic. Many of the ceramic panels are now in the possession of major museums in the west. They show specific historical scenes. There are also aesthetic compositions in the traditional miniature style which celebrate the joy of life and love.
The Chehel Sotoun Palace is among the nine Iranian Gardens which are registered as one of the Iran’s 17 World Heritage Sites. The nine gardens go by the name of "The Persian Garden".
