This paper examines the role of architecture as a narrative and ideological language in The Lord of the Rings, adapted from The Lord of the Rings. While previous studies have focused on mythology, adaptation, and visual aesthetics, this study explores how architectural spaces shape cultural identity, race, memory, and power in Middle-earth. Using qualitative textual and visual analysis, it compares Tolkien's literary descriptions with Peter Jackson's cinematic interpretation. The paper analyses four major architectural typologies-vernacular, naturalistic, grotesque, and archaeological-to demonstrate how settings such as the Shire, Rivendell, Mordor, and Minas Tirith contribute to characterization and narrative meaning. It argues that architecture in Jackson's adaptation is not merely a visual backdrop but an active storytelling device that constructs ideology, reinforces cultural values, and enhances the emotional experience of fantasy cinema.
