Apadana Persepolis was mostly built in the V century BC by Darius I and completed construction of king Xerxes I. the Image of both rulers remained at the East door of the complex.
The Palace complex of Persepolis was located on a high terrace carved into the rock, in the shape of an irregular rectangle, and was enclosed by a strong wall. Platform partly consisted of natural rock, part built from the side of the valley. Masonry of blocks of grey limestone, the usual building material for buildings of Persepolis, are connected by iron cramps, without mortar, and reaches a height of 8-18 m. the walls of unbaked brick from the outside were niches, three doorways were lined with massive stone blocks. The highest is the South doorway led to a large inner square.
At the end of the square stood a platform on which stood Apadana Darius – Xerxes. Apadana, or Grand columned throne room, is a huge tall building with an area of 10 square meters, the height of the main hall is about 20 m, square in plan with sides of 62.5 m. To the hall on three sides adjacent porticos, each with 12 columns (6 in a row). From two sides East of the portico stand two massive square towers. Powerful Apadana walls were built of mud brick, because poorly preserved. The ceiling of the room, made of cedar, covered with gold leaf, was supported by 36 stone columns with a height of about 18 m, base width of about 2 m, of which only 3 survived. A relatively small column width compared to their height and spacing of columns gives the impression of a large space.

The walls of the stairs Apadana lined with stone slabs covered in relief images.
