Within the medina, all sorts of functions are collected and integrated. All livelihood is within a walking distance.
Medina is human-sized, as prototype towns used to be.
It is a continuing tradition that our function-dispersed modern towns have left behind. Markets lined against the castle walls. The street is filled with every-day odour. Cars cannot enter the walls of the Medina. The modes of transportation used, to this day, are donkeys and horses.
