Le Duomo de Florence : mystère de la Renaissance
Florence, son Ponte Vecchio, sa Galerie des Offices et son Duomo. Célèbre dans le monde entier, le dôme de la basilique Santa Maria del Fiore domine la ville depuis le XVème siècle, mais sa construction conserve tous ses mystères. La coupole de la basilique florentine est la plus grande jamais construite en maçonnerie, plus grande même que celle du Capitole à Washington. Imaginée par Fillipo Brunelleschi, en 1419, cette œuvre architecturale est une véritable prouesse technique. Sa base octogonale de 41 mètres de diamètre s’avère être beaucoup trop large pour appuyer la voûte sur un cintre de bois, comme il était coutumier de le faire. Sa construction s’est faite sans aucun support. Six cents ans après, le mystère reste donc entier et l’on ne peut expliquer comment cette coupole a pu être construite sans structure de soutien. L’architecte Fillipo Brunelleschi avait tellement peur que son procédé inédit ne soit dévoilé qu’il emporta son secret dans la tombe.
Season 11 of Science grand format premieres in 12 days, on September 10, 2026, and the timing could not be better for viewers who like their prime-time television to feel both spectacular and genuinely informative. The long-running French documentary collection returns with a new run dedicated to major discoveries, scientific mysteries and historical investigations, opening with an ambitious space odyssey before turning to one of the most mythologized episodes in European history: Julius Caesar’s victory over the Gauls and Vercingetorix. If you follow factual series on BetaSeries, this is exactly the kind of premiere you will want to track early, because Season 11 already looks designed for viewers who enjoy documentaries that combine accessible storytelling with cutting-edge research.
For lapsed viewers, here is all you really need to remember before the new season begins. Science grand format is not a traditional serialized show with characters, cliffhangers or a single ongoing plot. Across its previous ten seasons and hundreds of episodes, the series has built its identity around standalone documentary events: French productions and international co-productions that explore archaeology, space, nature, ancient civilizations, technology and the big scientific questions shaping how we understand the world. It sits comfortably alongside programs such as Découverte, Le Monde de Jamy, Zeste de Science, The Complete Cosmos, Exploring Space or Ancient X-Files, but with a prime-time scale and a taste for immersive investigations.
That format is a real advantage heading into Season 11. You do not need to rewatch 349 episodes to be ready for the premiere. Instead, you can jump straight into the new season and let each episode function as its own expedition. What carries over from past seasons is the series’ core promise: experts, researchers, archaeologists, historians and scientists guide viewers through discoveries in progress, often challenging received ideas. The pleasure of Science grand format is not simply learning a fact; it is watching knowledge being tested, reconstructed and sometimes overturned.
