The Rococo movement came about in the 18th century in France as a way to fight against the strict, symmetrical Baroque style that came before it. While both movements are known for their richly decorated architecture styles, Rococo has elements all of its own: think curves, pale colors, and secular, light-hearted themes. The style made its way across Europe, where it found favor with the female rulers in St. Petersburg. The Catherine Palace (commissioned by Catherine I and expanded by her daughter, Empress Elizabeth) is by far the most famous example in the area.
