6St. Basil’s Cathedral (Moscow, Russia)

St. Basil’s Cathedral, with its colorful onion-shaped domes, is a symbol of Russia and a landmark of Moscow’s Red Square. 

Built in the 16th century by Ivan the Terrible to commemorate military victories, the cathedral is a striking fusion of Byzantine and Russian architectural styles.

Each of the cathedral’s nine chapels is crowned with a unique dome painted in vibrant colors, creating an almost fairy-tale appearance. St. Basil’s bold, eclectic design has made it one of the most visually distinctive buildings in the world.
