About St. Isaac's Cathedral

St. Isaac's Cathedral stands as one of St. Petersburg's most magnificent architectural masterpieces and one of the largest cathedral domes in the world. Commissioned by Tsar Alexander I in 1818 and designed by French architect Auguste de Montferrand, this neoclassical marvel took 40 years to complete. The cathedral's golden dome, visible from across the city, rises 101.5 meters high and is gilded with 100 kilograms of pure gold, making it an unmistakable landmark on St. Petersburg's skyline. The cathedral's interior is equally breathtaking, featuring an impressive collection of mosaics, paintings, and sculptures created by renowned Russian and European artists. With its 43 types of minerals and stones used in decoration, including malachite, lapis lazuli, and marble columns, St. Isaac's represents the pinnacle of 19th-century Russian imperial architecture. Today, it functions both as a museum and an active Orthodox church, offering visitors a glimpse into Russia's rich religious and cultural heritage.
