HYDRAULIC ENGINEERING STRUCTURES IN THE ARCHITECTURE OF MEDIEVAL AZERBAIJAN

Hydraulic engineering structures constituted an essential component of the architectural and urban heritage of medieval Azerbaijan, reflecting the high level of technical knowledge and environmental adaptation achieved by its master builders. This study examines the principal types of hydraulic structures, including kahrizes, ovdans, reservoirs, buzkhanas, and bridges, and analyzes their architectural, functional, and typological characteristics. Water-management systems played a vital role in urban development, agricultural production, trade, and everyday life, while also contributing to the aesthetic quality of the built environment. Kahrizes provided reliable underground water supply networks for major cities such as Tabriz, Ganja, and Baku, whereas ovdans and reservoirs ensured the collection and storage of groundwater and precipitation in arid regions and along caravan routes. Buzkhanas and snow-storage facilities demonstrate innovative responses to climatic conditions and the need for food preservation. Particular attention is given to medieval bridge architecture, distinguished by diverse compositional solutions, structural ingenuity, and harmonious integration with the natural landscape. Multi-span bridges, pointed arches, buttresses, and rhythmic spatial organization exemplify the synthesis of engineering efficiency and artistic expression. The study highlights hydraulic engineering structures as an important yet insufficiently explored category of medieval Azerbaijani architecture, underscoring their significance within the broader typological classification of the country’s monumental architectural heritage.
