Persepolis is a collection of magnificent palaces, the construction of which began in 512 BC and lasted 150 years. The glorious Achaemenid dynasty, which is one of the largest empires in the world, has inherited a huge capital of civilization for the world. The story of the construction of Persepolis Palace is also interesting and audible. 512 BC Achaemenid king Darius chose a large rock in the northwest of Mount Mehr to build a magnificent palace. Choosing the location of the palace was one of the most accurate and elaborate choices. Because the astronomical position of the mountain, the angle of sunrise and sunset, the presence of high mountains and green plains and, most importantly, being on the path of the royal road, made it the best possible place. This magnificent palace, with its antiquity, is still considered as one of the most beautiful historical monuments left from ancient times.
