The temple of the Sagrada Familia, under construction since 1882 and situated in the Eixample district of Barcelona, is the most important work of Antoni Gaudi. It is a great monument to spirituality, where every detail, however small, has symbolic value. Its three main facades, crowned by towers, contain a mass of details full of symbolism and mysticism. The temple, which was inspired by medieval cathedrals and their Gothic style, is the most-visited monument of Barcelona. This book describes the history and secrets of this universal monument.
