Hall of Xerxes - Persepolis
The Hypostyle Hall of Xerxes, of which this is a reconstruction, served as a throne-room or hall of audience; it was open air all year round, but the spaces between the columns could no doubt be closed with gorgeous hangings on the sunny side. Detached columnades surrounded it on three sides, the style of the pillars being slightly different from that in the body of the hall; they were all, however, crowned with double bull's head capital, and their height was 65 feet.
columns were of similar imposing size to those of the Temple
of Jupiter Heliopolitanus at Baalbek.
