This publication explores the concept of utopia, a historical aspiration to establish an ideal order that transcends the contradictions of reality. Initially introduced as a form of narrative fiction, utopia frequently manifests in the design of cities, envisioned by architects as spaces epitomizing rationality and embodying ideals of perfection, progress, equality, and universal virtue. However, when such visions are implemented, they often drift towards authoritarian or totalitarian regimes. With this intriguing tension as its backdrop, the publication investigates the evolution of utopian city concepts from ancient times to the present day. Following the success of its original Turkish edition, this insightful work has been translated into English to reach a broader audience. It is enriched with critical analyses by renowned scholars such as David Turnbull, Emre Arolat, Davide Ponzini, and Tim Cutts.
