Antoni Gaudí, an architect with a very strong personality and with an incomparable imagination for forms, was also a first class constructor, capable of introducing innovations into traditional styles and finding other solutions that met the needs of his time and, indeed, those of the future. This book takes a tour of the Temple of the Sagrada Família--his most emblematic and popular work, to which he devoted more than 42 years of his life--, in order to discover the innumerable details that characterise it, just as Gaudí left it at the time of his death, as well as its continuation, undertaken using current techniques, something that demonstrates the feasibility of his fantastic project.
