According to Wikipedia, Chehel Sotoun ("Forty Columns”) is a pavilion in the middle of a park at the far end of a long water pool, in Isfahan, Iran.  Built by Shah Abbas II (1632-1666), this palace was used for his entertainment and receptions. In this palace, Shah Abbas II and his successors would receive foreign dignitaries and ambassadors, either on the terrace or in one of the reception halls.  The name itself means "Forty Columns" in Persian language, was inspired by the twenty wooden columns supporting the entrance pavilion, which, when reflected in the waters of the fountain, are said to appear to be forty.
