The Travelling Gardens project aims to examine the extent to which historical, cultural, political, and commercial connections between the seat of the Abbasid caliphate ‎in ‎‎Lower Mesopotamia and the powerful eastern region of Khorasan (now divided between modern Iran, Turkmenistan, and Afghanistan) led to an exchange and/or modification in concepts of palace gardens at the heart of pre-Mongol Western Asia. To facilitate this multifaceted investigation, it comprises three research prongs, each focusing on a specific objective: First, it examines the geopolitical configuration of the Abbasid caliphate with its dense networks of exchange and encounters between Khorasan and Lower Mesopotamia. Second, it investigates specific formal and functional features of palace gardens in Khorasan in terms of their environmental, architectural, and transregional contexts. Third, it offers a comparative and anthropological analysis of these gardens’ features with those in Lower Mesopotamia (illuminated in my previous work), focusing on cultural interactions between these two regions and their respective geographical characteristics. Based on these royal gardens, which nevertheless strongly depend on their physical, cultural, and human geography, this project provides a noble perspective for gaining new insights into cultural and material ‎‏exchanges within the Abbasid Caliphate. Furthermore, it fills a significant gap in the global history of garden architecture and sheds new light on various factors that affected the design and function of these highly representational built environments.
