Complete Guide to St. Isaac's Cathedral in Saint Petersburg

About St. Isaac's Cathedral

St. Isaac's Cathedral stands as one of Saint Petersburg's most magnificent architectural masterpieces and one of the largest Orthodox basilicas in the world. Built between 1818 and 1858 under the direction of French architect Auguste de Montferrand, this colossal neoclassical cathedral dominates the city's skyline with its massive golden dome that can be seen from miles away. The cathedral required 40 years to complete and employed innovative engineering techniques for its time, including the use of steam-powered machinery to lift the enormous granite columns. The cathedral serves both as an active place of worship and as a state museum, showcasing extraordinary artistic and architectural achievements. Its interior houses one of the world's largest collections of mosaics and paintings, created by prominent Russian and European artists. The building's impressive statistics are staggering: it can accommodate up to 14,000 people, features 101.5-meter-tall dome, and required approximately 100 kilograms of gold to gild its exterior dome, making it a true testament to Imperial Russia's grandeur and artistic ambition.
