Milan Cathedral Took 600 Years to Build. No Machines. No Architect Lived to See It Done.
What kind of building takes six centuries to complete? Construction of Milan Cathedral began in 1386 with a vision far larger than anything the city had ever attempted. Thousands of sculptures. Endless spires. A design so complex it kept changing as it was being built. And it never really stopped. This video reconstructs how medieval builders constructed Milan Cathedral — from the early foundations to the generations of workers who continued the project long after the original plans were forgotten. No machines. No consistent plan. No guarantee it would ever be finished. Just stone, time… and a structure that kept growing anyway. Some scenes in this video are AI-assisted reconstructions based on historical research.
