I think Persepolis was my least favourite place we visited. I was fascinated by the scale of everything, but I wish I have done my research before I went to appreciate it even more. Plus going there between 10am and 1pm was not a great idea because that is when the sun hit its hottest. Although, it was September. I think going in the afternoon around 4pm will be a more ideal time for hotter months.
Persepolis was built by Darius I in 518 B.C as the capital of Achaemenid Empire. The thing that resonated with me the most was the thoughtful design. For instance, the staircase leading up was designed to purposefully make the steps of the visitors slower and more dignified.
My visit was about three hours because it is a huge place and there is a bit of climbing up to enjoy the view to the fullest. That was the most enjoyable part for me because my friends and I got to fool around and pretend we were flying in the refreshing breeze.
