Episode 9 - Dome

This film reveals the technological leaps forward that have allowed the world’s largest spanning dome – the Oita Stadium in Japan – to be built. The Oita’s colossal roof spans a mighty 274 metres. A steel, Teflon and titanium structure over 270 metres across, and 60 metres high, the Oita Stadium roof covers a sports stadium big enough to seat 43 thousand spectators.  At the flick of a switch its seats retract to reveal a running track and its roof opens and closes like a giant eye. This film explores how this building was made possible through a series of six engineering breakthroughs. The film explores how six landmark buildings – including the Pantheon in Rome and Florence Cathedral – each feature a major technological innovation that allowed engineers to build bigger Domes. Using high-end computer generated imagery that makes up 50% of the film, this film reveals the incredible stories behind these super domes and the inventions that have enabled them to grow ever larger. Six ingenious leaps forward that enabled domes to evolve …from BIG to BIGGER into the World’s BIGGEST."
