This publication takes a tour of the religious work of Miguel Fisac ?? in four moments: an initial period with his works for the CSIC and the works for the Dominicans in Valladolid and Alcobendas. A second pre-conciliar stage and a third that includes the development of projects with the new impetus of the Second Vatican Council. A final stage with small projects that completes a particularly intense trajectory, and of exceptional quality. The book is, at the same time, a journey through the history of Spain from the end of the Civil War to the eighties, through the history of the Spanish church and its evolution, through the history of construction technologies and processes and through the personal history of Miguel Fisac. 202 p.: photo, Color, 23x15 cm., paperback
