(The Versailles hall was originally intended to be a two-storey building, but a third floor was eventually added. The story where the wedding took place was initially intended to be a roof, and hence was not designed to carry the same load as the other levels.) - The structure was built using the "Pal-Kal method," which has since been outlawed as a result of the tragedy. (Pal-Kal method is a cheap, lightweight construction method that uses metal plates and thin layers of cement.) - Leftkovits, E.
