Saint Isaac's Cathedral. Colonnade of Montferrand
This is not the only work of the master. The famous French architect left another legacy in both Russian capitals. However, by uniqueness, nothing can be compared with St. Isaac's Cathedral. An unrivaled masterpiece are its colonnades. The building data of all four portals immediately sets the scale of the values ββand reminds everyone who enter that he came to the Temple of God. They amaze the imagination with their power.

However, the viewer is even more shocked when he looks from the bottom up at St. Isaac's Cathedral. The colonnade under the dome goes to the skies and reminds of eternity, the mortality of earthly existence. In addition to the stunning artistic expression of the main cathedral of the capital of the Russian Empire, it is impossible not to think about the engineering aspects of its construction. And the temple was built on the technology of the early nineteenth century. Column granite of suitable quality was found on the shores of the Gulf of Finland near Vyborg. From there, monolithic blocks were delivered to the capital on barges specially built for this purpose. Montferrand developed special lifting mechanisms for their installation, which had no analogues in European practice. Of particular difficulty was the rise of monolithic columns to a height. Namely, under the dome, which crowned St. Isaac's Cathedral. The colonnade at this height to this day inspires great respect for the engineering genius of a Russian architect of French origin. And to the simple Russian hard workers of serf status, who built all this, and mostly in manual mode. And many of them put their lives on the construction of this temple. 60 craftsmen died only when gilding a unique dome from poisoning with mercury vapor.
