'Forty Columns') is a Persian pavilion in the middle of a park at the far end of a long pool, in Isfahan, Iran, built by Shah Abbas II to be used for his entertainment and receptions.
In this palace, Shah Abbas II and his successors would receive dignitaries and ambassadors, either on the terrace or in one of the stately reception halls.
They depict specific historical scenes such as the infamous Battle of Chaldiran against the Ottoman Sultan Selim I, the reception of an Uzbek king in 1646, when the palace had just been completed, the welcoming of the Mughal Emperor Humayun who took refuge in Iran in 1544, and the Battle of Marv in 1510 where the Safavid Shah Ismail I vanquished and killed the Uzbek king.
[3] In the pavilion, the combined designs of the walls and ceiling of the hall, which are placed in Lachak Toranj (corner and medallion), and the main lines of the building divisions, which are a combination of painting, tiling and other various decorations, make the building one of the best examples of Persian architecture during the Safavid era.
At present, the mansion operates as a museum; and its central hall displays some works of art from different periods of Iran.
