One of the most prestigious cultural institutions in the country, the Mariinsky Theater, has been dazzling opera and ballet goers since it was founded in 1859. A fitting setting for all the world-class dancers, singers, and musicians that have performed on its stage over the decades, the lavishly decorated concert hall really is a delight to gaze upon. Named after the wife of Tsar Alexander II, the Mariinsky Theater is one of the best places in Saint Petersburg to watch a show.
