Lenin's Mausoleum in Moscow, Russia, is a significant historical landmark and a prominent feature of the Red Square. It is the resting place of Vladimir Lenin, the revolutionary leader and founder of the Soviet Union. The mausoleum was constructed shortly after Lenin's death in 1924 and was designed by the architect Alexey Shchusev. It is a somber, squat structure made of red granite, black labradorite, and other materials, symbolizing the colors of the Soviet flag. Inside, it houses a glass sarcophagus where Lenin's embalmed body lies on display, which has been maintained since his death. The mausoleum has been a place of pilgrimage for communists and curiosity-seekers alike. Visitors come to observe the preserved body and contemplate the legacy of one of the 20th century's most influential figures. It is also a site of political importance, where Soviet leaders would stand atop during parades. However, access to the mausoleum can be limited, and it is occasionally closed to the public for maintenance of Lenin's body or for official state functions.
