Achaemenian presence in the Transcaucasia (south Caucasus) and cultural area of Black Sea based on architectural findings

New conducted archaeological excavations in the cultural area of Black Sea and South Caucasus indicate accumulation of Achaemenid artistic data and the effects of Persian style in architecture that include palaces, columned halls, columned room, gates, and rockcut tombs. Achaemenid traces and the traces which related to the new art families in the cultural area of Black Sea were taken from different regions such as Anatolia, Ukrain, Russia, Bolgaria, Georgia, Armenia and Azarbaijan. At Satrapi of Thrace, Borysa and Doriskos along with a royal residence were built. In Pontus and Oluz Höyük, Achaemenid palaces with column base were made; in Qaracamirli, Azerbaijan, east and central Georgia, historical monuments similar to Achaemenid cases and rockcut tombs affected by Achaemenid architecture have identified in Anatolia. We see a sort of unity in construction and decoration in the obtained works of cultural area of Black Sea that, due to the volume of Achaemenid architecture works, the need for a comprehensive, scientific, and objective research will pose in this regard. The questions raised in this study are: 1- How does the Achaemenid art and architecture affect the architecture of the Black Sea and the South Caucasus in the Achaemenid era? 2- How to form the art style "Ionic - Achaemenid" on the architectural monuments of the cultural zone of the Black Sea and the South Caucasus in the Achaemenid era? Are. The results of this research show that following the Achaemenid court style, the Achaemenid architecture has been harmonized in the field of study. Also, in the western part of Anatolia, after the formation of a new artistic style called Ionian-Achaemenid, it has had a direct impact on the architecture of this period in the field of study. This study has been fundamental. By descriptive-analysis method and documentation of data based on quantitative methods and analyzing data, Achaemenid architecture analysis will be discussed in the field of study.
