Persian Empire ( Persepolis) - Part 1

Persepolis is near the small river Pulwar, which flows into the river Kur (Kyrus). The site includes a 125000 square meter terrace, partly artificially constructed and partly cut out of a mountain, with its east side leaning on Kuh-e Rahmet ("the Mountain of Mercy"). The other three sides are formed by retaining walls, which vary in height with the slope of the ground. From 5 to 13 meters on the west side a double stair, gently slopes to the top. To create the level terrace, depressions were filled with soil and heavy rocks, which were joined together with metal clips. Around 518 BC, construction of a broad stairway was begun. The stairway was planned to be the main entrance to the terrace 20 meters above the ground. The dual stairway, known as the Persepolitan stairway, was built in symmetrically on the western side of the Great Wall. The 111 steps were 6.9 meters wide with treads of 31 centimetres and rises of 10 centimetres. Originally, the steps were believed to have been constructed to allow for nobles and royalty to ascend by horseback. New theories suggest that the shallow risers allowed visiting dignitaries to maintain a regal appearance while ascending. The top of the stairways led to a small yard in the north-eastern side of the terrace, opposite the Gate of Nations. Gray limestone was the main building material used in Persepolis.
