Book excerpt: From ancient palaces and glorious cathedrals, to futuristic homes and striking skyscrapers, architecture continues to play an important role in the development of history and culture. Architecture Inside + Out examines fifty of the world's most impressive buildings and uncovers their structural secrets through detailed illustrations, while clear and accessible text places each building in its context. By researching original plans, notes and drawings, this book reveals the expertise and original intentions behind these magnificent creations, simulating the experience of spending time with the architects themselves.However, a building truly comes alive once it is inhabited, and Architecture Inside + Out also looks beyond the bricks and mortar to explore the principal spaces within. Photographs of striking interiors enable readers to scrutinize the most awe-inspiring aspects of these structures. The reader will discover how ancient wonders, such as the Parthenon and Colosseum, were constructed; learn the colour-coding behind the exposed skeleton of the Centre Pompidou in Paris; understand the vision behind the Brutalist housing complex, Habitat 67, in Canada; and take a tour through the Capitol Building in Washington, the seat of the United States Congress.
