The official narrative is that over 200 huge buildings were built for the Chicago Worlds Fair only to be torn down a few years later. Everyone believes that story, even though they wouldn't have been able to even complete the foundations of the buildings in time for the fair with 1893 machinery.

Also i used to believe the lie about the world fairs being just built quickly but then i started looking at actual photos. Even if built from wood only and plaster theres no way to do it. Only if youre inly building a couple buildings and the rest are just getting cleaned up/painted white and getting a new roof
