Forgotten technologies of column casting / Andrey Kadykchansky
Andrey Kadykchansky conducted a study of the columns of St Isaac's and Kazan Cathedrals, as well as the Alexandria Column, using a thermal imager. As a result, it was possible to find out that the columns were not made of solid pieces of granite, but have a composite structure and are faced with plaster. This discovery contradicts official history. Who and why is hiding the real methods of building ancient structures?
