History
The first St.
Isaac's church in Saint Petersburg was a modest wooden structure consecrated in 1707, named after the city's founder Tsar Peter the Great's patron saint.
It was replaced by a stone church in 1717, which stood until structural issues led to its demolition in 1763.
Empress Catherine the Great commissioned a new Baroque-style cathedral in 1768, which took 34 years to complete but was later deemed disproportionate.
In the early 19th century, a design competition led to the selection of Auguste de Montferrand's neoclassical design.
Construction of the current cathedral began in 1818 and was completed in 1858, marking a significant achievement in Russian architectural and engineering history.
