The Council Hall, the Gate of the Kings, the Three Gates, the Three Doors or the Central Palace are located in the center of the Persepolis Royal Palace. Earlier, the building of this palace was attributed to Darius the Great, but there are good reasons that its complete construction was done by Ardashir I.
In the lithographs of the stairs of this palace, Persian elders and nobles are depicted who visit the king informally and in a friendly way.
