How Was Windsor Castle Built: Surviving 900 Years of War and Fire

November 20, 1992. Fire tears through Windsor Castle, destroying over 100 rooms in just hours. Medieval roof voids turn into hidden chimneys. St. George’s Hall collapses. Nine centuries of history burn. But Windsor had burned before. And rebuilt before. And transformed before. This film traces how Windsor Castle survived nearly 1,000 years — not through perfect design, but through constant reinvention. From: William the Conqueror’s 11th-century earth motte built by forced labor Henry II’s radical gamble of placing thousands of tons of stone on compressed soil Edward III’s plague-era Gothic megaproject funded by war Victorian architects hiding industrial iron inside “medieval” stone to the 1992 fire and the largest green oak roof built in Britain since the Middle Ages Using immersive AI-generated visualizations, this video reconstructs each engineering transformation — the artificial hill, the shell keep, the flying buttresses, the hidden iron skeleton, and the modern fire-resistant restoration that protects it today. Windsor Castle didn’t survive by staying the same. It survived because every generation was willing to tear it apart and build it again.
