The Moscow Metro is famously known as the "Underground Palace" or the "People's Palace," a nickname that reflects the stunning, lavish architecture of its historic stations. When the system first opened in 1935, Soviet architects designed the stations with marble walls, intricate mosaics, massive chandeliers, and bronze statues to serve as a showcase of Socialist Realism and the supposed bright future of the Soviet citizen. Beyond its unofficial nicknames, the system has a very long official name: the "Moscow Order of Lenin and Order of the Red Banner of Labor V. I. Lenin Metro." This is usually shortened in official contexts to simply the "V.I. Lenin Metro." While modern stations are built with a more contemporary aesthetic, the nickname "Underground Palace" remains the most common way locals and tourists describe the world-renowned 1930s-era stations like Komsomolskaya or Mayakovskaya. It is not just a transit system but one of the most visited cultural landmarks in Russia, handling over 7 million passengers daily.
