Lenin's Mausoleum (from 1953 to 1961 Lenin's and Stalin's Mausoleum) (Мавзолей Ленина), also known as Lenin's Tomb, is a mausoleum located at Red Square in Moscow, Russia. It serves as the resting place of Soviet leader Vladimir Lenin, whose preserved body has been on public display since shortly after his death in 1924, with rare exceptions in wartime. The outdoor tribune over the mausoleum's entrance was used by Soviet leaders to observe military parades. The structure, designed by Alexey Shchusev, incorporates some elements from ancient mausoleums such as the Step Pyramid, the Tomb of Cyrus the Great and, to some degree, the Temple of the Inscriptions. Two days after Vladimir Lenin's death on 21 January 1924, architect Alexey Shchusev was tasked with building a structure suitable for viewing of the body by mourners. A wooden tomb, built in Red Square close to the Moscow Kremlin Wall, was ready on January 27, the same day Lenin's coffin was placed inside. More than 100,000 Soviet citizens visited the tomb in the next six weeks. By the end of May, Shchusev had replaced the tomb with a larger, more elaborate mausoleum, and Lenin's body was transferred to a sarcophagus designed by architect Konstantin Melnikov. The new wooden mausoleum was opened to the public on 1 August 1924. Pathologist Alexei Ivanovich Abrikosov had embalmed Lenin's body shortly after his death, with Boris Zbarsky and Vladimir Vorobiev later being tasked with its ongoing preservation. Zbarsky was soon assisted by his son Ilya Zbarsky, a recent graduate of Moscow University, who likened the work on Lenin's body to that of ancient Egyptian priests. In 1925, Boris Zbarsky and Vorobiev urged the Soviet government to replace the wooden structure after mold was found in the walls and even on the body itself. A new mausoleum of marble, porphyry, granite, and labradorite, designed by Shchusev, was completed in 1930. The mausoleum also served as a viewing stand for Soviet leaders to review military parades on Red Square.
