We often think of Napoleon Bonaparte as the incredible legislator and war leader, but we tend to forget that he was a prolific patron and instigated many constructions that are anchored in the Parisian landscape. The Arc de Triomphe, the Vendome Column, the Palais de la Bourse, the church of La Madeleine, the building of bridges and piercing of canals. This film tells the story of these megastructures that we owe to Napoleon. How many architects, sculptors, workers, had to be called for these constructions? How to build such imposing sites in the heart of Paris? How long did these construction works last as they were often disturbed by an unstable political context? Why were these changes necessary? What innovations in terms of materials and what technical prowess their constructions engendered? Examine these questions. Let's throw it back to the extraordinary transformations of the First Empire, a precursory work that will be extended and amplified during the Second Empire.

Napoleon III had one ambition to modernise the whole French capital city. Why? Because he had lived in London, a city that impressed him, and that Paris at the time was simply the opposite, a huge putrefaction workshop, where misery, plague and diseases worked together, with no room for the air or the sun to break. Napoleon employed Georges-Eugene Haussmann, who seemed to be the right man for the job, to take on a mission to aerate, homogenise and embellish Paris. How did they do it? Which revolutionary transformations did they undertake?

In 1858, Virgin Mary appears 18 times in the Grotto of Massabielle. At first, nobody believes it, but when the Catholic Church recognised the place, the construction of one of the biggest Christian complexes begins, and pilgrims rush to visit it... Today, it is the second most visited Catholic complex with about 600000 visitors per year. How did the architects manage to build big enough structures to welcome all these believers? 52 hectares, is the surface area on which the domain of the sanctuary spreads. It includes natural places such as the grotto, as well as monumental structures built by men: 15 pools, a church, no less than three basilicas, and a 1500 metres-long Stations of the Cross. Let's get back to the construction of these extravagant edifices. Four religious edifices were built one after another. The Basilica of the Immaculate Conception in 1866, the Rosary Basilica in 1881, the Basilica of St Pius X in 1956, and finally, the church of St Bernadette in 1986. All built in different styles and different times, what technical challenges had to be risen to for these constructions to see the light of day? What difficulties were encountered during the works? This film is the incredible story of a serious challenge: how to succeed in welcoming hundreds of thousands of believers while respecting and resisting the hostile natural environment of the Gave de Pau river.
