Towering above the city skyline, this architectural masterpiece draws millions of visitors each year who come to admire its artistry, panoramic views, and fascinating past. For travelers seeking the best things to do in St. Petersburg, a visit to Saint Isaac’s Cathedral is essential.
History of St Isaac’s Cathedral
The origins of Saint Isaac’s Cathedral date back to 1707, when Peter the Great commissioned a modest wooden church to honor his patron saint, Isaac of Dalmatia. Over the centuries, the cathedral was rebuilt several times due to flooding, lightning strikes, and the city’s rapid growth. The current structure—the fourth incarnation—was conceived by Tsar Alexander I, who envisioned a grand cathedral befitting the Russian Empire’s new capital.
In 1818, French architect Auguste de Montferrand was selected to design the new cathedral after submitting 24 different proposals in various styles. Construction was a monumental feat, lasting 40 years and requiring innovative engineering to stabilize the building on St. Petersburg’s marshy land. Workers drove over 25,000 wooden piles deep into the ground to create a solid foundation. The cathedral was finally consecrated in 1858, just a month before Montferrand’s death—a twist that became part of local legend.
During the Soviet era, Saint Isaac’s Cathedral was transformed into a Museum of Atheism and its religious icons were removed. Remarkably, the building survived World War II unscathed, despite the city’s heavy bombardment. Today, it serves as both a museum and a functioning Russian Orthodox church, symbolizing the resilience and grandeur of St. Petersburg.
