The amazing stone curving in Apadana, Persepolis. I can not imagine someone in 2500 years ago doing this. Even today it can be expected machine made.

The gretest palace in persepolis. These columns are 20 meters high and they are one part curved stones. My tripod on the remains of one of the bases shows the size.

Information from Persepolis3D.com
Gate of all lands (nations) was the main gate for guest to arrive to the the city of Parsepolis.
The Grand Stairway, the Gate of All Nations, the Avenue of the Army and the Throne Hall are all parts of a concept. Together they form the processional route of the army from the level of Marv-Dasht to the Throne Hall and back. One can vividly imagine the formations of soldiers marching between the Throne Hall and the Army Gatehouse and further through to the Gatehouse flanked by the huge carved stone bulls of the southern portal, then through this building and exiting through the north portal and into the arrow-straight Avenue of the Army heading west toward the Gate of All Nations - there greeted by the huge winged bulls with human faces. From the exterior of the grounds on the level of the Marv-Dasht an observer would be offered an impressive display: the "Immortals" marching through the stone bull guarded west portal of the Gate of All Nations and on to the Grand Stairway. Here, the rows of soldiers would split left and right marching down the seven meter wide stairs in perfect step with the drumbeat. Upon arrival at the mid landing they would turn 180 degrees and rejoin into single rows. With their colorful clothing and banners and the sunlight reflecting off of their armour they would have resembled two slow flowing rivers splitting and then reuniting.
