The ruins of the great city of Persepolis are at the foot of the mountain, Kouh-e-Rehmat, or 'mountain of mercy'. Persepolis is the same as Parsa, which means 'City of the Persians'. The origin of Persepolis can be traced to 515BC to serve as the capital of Archaemenid Empire. It is located 70km in the north of Shiraz, Iran.
The ordinary man found it difficult to make it to Parsa specially in the rainy season because the path lay through some mountains. Therefore, the city came to be used as a summer and winter capital.
Almost all of the administration work of the Achaemenian Empire was conducted from Susa or Shush, Iran. Administrative offices were stationed in Babylon and in Ecbatana in the winters. This is probably why Parsa remained out of the sight of the Greeks. It was only when Alexander the Great plundered and looted Parsa in 330 BC that the place came to the notice of the world.
Scholarly investigations into the mysteries of Parsa were initiated in 1931. Several excavations were made. The studies went on till 1939, the year that saw the beginning of the Second World War in Europe and the world over.
Architecture in Persepolis has mainly wooden columns. The artisans in Parsa used stones for construction only in cases when wood from the trees of Lebanon or India did not fulfill the requirements. A comprehensive structure standing on a stone framework was erected due to paucity of wood. But a fire is believed to be the cause of the end of the Parsa empire in Persia.
