This book addresses the multiplicity of architectures that have taken place in Mexico during the 20th and early 21st centuries. In accordance with the idea of ​​effective history of the French philosopher Michel Foucault, in which knowledge, like history, does not encompass absolute truths but fragments, a reading of the different themes that make up architectural production is presented. Based on this approach, an understanding is sought beyond the built forms and close to the ideas that generate them. In an attempt to make paradigms shift and reinvent themselves, history is seen as a place to work, with an emphasis on the relationship between architecture, theory, art, design and urbanism.
