Persepolis "The Main Hall and Gateway to All Nations" One of the Marvels of Persepolis     SinceThe center of the great Persian Empire, ceremonial capital of the Ach嬥nians, and the masterpiece of Ach嬥nian art, Persepolis, is the greatest monument indicating the glory and magnificence of the ancient Persian. One of the most significant architectural components of Persepolis “The Main Hall and Gateway to All Nations” was essentially constructed for holding new-year (Now Rooz) celebrations.   SinceOn this day, the heads of states, governors and guests from all over the Persian Empire would come to express their greetings and presents their gifts to the king. On the morning of Now Rooz, during a grand ceremony, the king, wearing his crown, would get his royal powers approved by Ahura Mazda (God of goodness and possession).   SinceIt was the duty of the king to continually fight against evil demons and suppress them so that he would be worthy and competent to rule in the coming year. The Now Rooz guests would slowly ascend the massive stairways to the palace and upon reaching the vast leveled area of the Main Hall and Gateway to all nations would proceed to enter the magnificent Apadana Palace. The Gateway to all nations is a radiant example of dialogues among the representatives of all civilizations in the beginning of the third century. The Gateway to all nations was constructed during the reign of Xerxes I. Two stone winged bulls with the faces of two bearded men in Babylonian caps can be seen in front of the doors. They were supposed to be symbols of the divine guards of Persepolis.
