This book describes the geotechnical aspects for correcting the geometry of Mexico City´s Metropolitan Cathedral and of the adjoining Sagrario Church. It describes the main aspects of geotechnical conditions in the city and of the most important hazards affecting these monuments. It discusses the analyses performed and the actions taken to achieve the corrections required. The book aims to provide non-specialists with a clear picture of the magnitude and importance of the project and of the achievements it fulfilled. It is expected that the book will also appeal to specialized geotechnical engineers that will be provided with references to follow up the project in depth. The book will contain a large number of illustrations and will be written so as to provide "down to earth" explanations of the basic theories applied and of the actual construction procedures
The work will appeal to both students and professionals in the fields of Architecture and Civil Engineering. It will also interest specialized audiences of geotechnical engineers and conservation architects and it may also be of value to art historians.

This is a series of short books on specialized topics that fall under the overarching theme of built heritage and geotechnics, like well documented case studies of restoration works at one specific site or of a monument, or detailed overviews of construction techniques, intended as a material witness of knowledge of the historical period in which the monuments were built, or specific conservation / preservation works.
Preservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical and economical aspects in inextricable patterns. The complexity of the topic is such that a shared framework of reference is still lacking among art historians, architects, structural and geotechnical engineers. This is proved by the fact that, despite there being exemplary cases of an integral saving of any structural components with its static and architectural function, as a material witness of the knowledge, the culture and the construction techniques of the original historical period, there are still examples of uncritical confidence in modern technology which leads to the replacement of previous structures with new ones, which only preserve an iconic appearance of the original monument.
For this reason publishing short books on specialized topics, like well documented case studies of restoration works at one specific site or of a monument, or detailed overviews of construction techniques, intended as a material witness of knowledge of the historical period in which the monuments was built, or specific conservation/preservation works, will be of great value.
