Saint Isaac's Cathedral

St. Isaac's Cathedral in St. Petersburg, Russia is the largest cathedral in that city and was the largest church in Russia when it was built (101.5 meters high). It was dedicated to Saint Isaac of Dalmatia, a patron saint of Peter the Great who had been born on the feast day of that saint.

Technologies

Many technological innovations were used in the construction of the building. The massive portico columns were raised with the use of enormous wooden frameworks before the walls were erected. The dome was gilded by a technique similar to spraypainting; the solution used included toxic mercury, the vapors of which caused the deaths of an unknown number of workers. Over a dozen gilded statues of angels, each six metres high, face each other across the interior of the rotunda. They were constructed using galvanoplastic technology, making them only millimeters thick and very lightweight. St. Isaac's Cathedral represents the first use of this technique in architecture.
