in the palaces in the city of Pasargadae during the Achaemenid era and the role of kings in changing
them through different periods of time, especially the royal palaces. This research is shedding light
on the most important urban changes that occurred for the palaces in the city of Pasargadae and

in relation to previous studies clarifies that other researchers dealt with the city of Pasargadae as a
historical city and some of them dealt with the archaeological aspect of it. In the present research,
the focus is on how they developed these palaces. The method of analysis used in this research is
following the historical and descriptive aspects of these palaces and mixing them by highlighting
the most important urban aspects of them. Results show the most important feature of our
research which is knowing the most prominent methods that were used in the development of
