Parabeton – Pier Luigi Nervi and Roman Concrete begins with the earliest surviving concrete dome from the 1st century BC in Baiae, near Naples. It then presents 17 buildings by Pier Luigi Nervi (1891-1979), a master of concrete architecture. Featured structures include the Pirelli skyscraper in Milan, UNESCO Headquarters in Paris, Palazzo del Lavoro in Turin, Palazzo dello Sport in Rome, and the Papal Audience Hall in Vatican City. The film intermittently examines significant Roman buildings like the Pantheon, Baths of Caracalla, and Hadrian's Villa, linking Nervi’s innovative work with ancient Roman concrete architecture.
