St.Louis fair in the United States, 1904.

The narrative claims that these buildings were created within a few years in the time of primitive technology... which is an obvious lie, and after every fair / exhibition almost all the buildings were destroyed.

First question arises why would America copy Roman Style, and then destroy it after few years?

The answer is this is not Roman style. This is much prior to the Roman building. White folk were living in America way before Christopher Columbus officially discovered it.

They stole our buildings, and our History. Tartarian culture had to be buried at all cost.
