This lecture explores the origins of the Futurist movement and the ideas that defined its architectural vision through the Manifesto of Futurist Architecture (1914). It examines the contributions of key figures such as Filippo Tommaso Marinetti, Antonio Sant'Elia, and Umberto Boccioni, while critically analysing the manifesto's radical principles, its limitations, and its political and ethical implications. The lecture also considers the enduring influence of Futurist ideas on contemporary architectural discourse and the continuing role of manifestos in shaping architectural thought.
