’The subject of unbuilt utopian cities is fascinating. While built cities may survive for centuries, they are vulnerable to decay and destruction through natural forces, or, in our increasingly dystopian global society, through war and terrorism. Unbuilt, they hover endlessly between the potential and the actual. Tessa Morrison’s approach is both scholarly and accessible. The illustrations are illuminating, and the historical context for the evolution of the ideas is explained. This challenges the reader to consider the utopian plans from the perspective of their creators, who were imagining the future, rather than analysing them with the benefit of hindsight.’ Lorna Davidson, Director, New Lanark Trust and Hon. Secretary of the Utopian Studies Society (Europe)
