Fantastic Architecture is where myth, imagination, and built form collide. From the haunted labyrinth of the Winchester House to Gaudí's dragon-roofed Casa Batlló, from Dante's descent into Hell to Saudi Arabia's futuristic Line, Mustansir Dalvi traces how architecture becomes a vessel for stories, dreams, and anxieties. Moving between literature, cinema, visionary drawings, and real buildings, this monograph reveals how the fantastic exposes what we most desire-and fear-in our cities.
