The metro opened in 1935. Many entrance buildings are just as architecturally spectacular as the stations below. Some stations are very deep and have been planned to serve as bomb shelters.

Moscow's metro stations are a heritage of the socialist regime, originally intended to be 'palaces for the people'. With their marble-clad walls, chandelier lighting, and other precious interior, many indeed resemble palaces or cathedrals [metro.ru], [metrowalks.ru], [beeflowers].

Many sculptures, reliefs and murals are found in the stations [metrosoyuza.net]. Besides Moscow, some other cities of the former Soviet Union have metro stations of similar grandeur. However, the ones in Moscow are the most numerous and the most spectacular. Fortunately, even the new stations opened in the 21st century are of good architectural quality.
