This book explores how the River Danube has been imagined, narrated, and contested across various media from the nineteenth century to the present day. The authors consider how political borders, technological projects, and cultural perspectives shape the river's significance, and examine the interaction between dominant narratives and local, regional, and ecological deviations. Drawing on literary texts, travelogues, photographs, postcards, films, and unpublished archival sources, the study explores the Danube as both a physical waterway and a medium of cultural communication. It traces changes in landscapes, infrastructure, and sites of memory, revealing how visions of modernisation, heritage, and identity are negotiated along its course. Integrating literary, visual, and performative perspectives, the book presents the Danube as a dynamic space where diverse histories converge, overlap, and confront each other.
