Abstract
Although the Islamic palace complexes considered the pearl of architecture, even though they are studied separately by scholars for years and centuries, their unity in one direction of architecture has been neglected so far. For this reason, we have tried to explore the architecture of palace complexes, which is considered to be the most beautiful examples of the magnificent Islamic architecture, to reveal their similar features, and to reflect the influence of these buildings on the formation and development of the urban planning composition. Palace complexes built in almost all the states that adopted Islam in the Middle Ages were planned to be the core of the city based on the same laws. The main purpose of the study is to explore the architecture, history and composition structure of the great Shirvanshahs, Topkapi Palace, Alhambra and Akbari Sarai palaces built in the Middle Ages and to reveal their similar features. In the study, it was proved that the architecture of the palace complexes that survived until today was built in the same styles, that Islam has its own architectural laws and that these laws are applied more accurately in palace construction.
