Two days after the death of Joseph Stalin the Politburo decreed placing his remains on display in the Mausoleum; it officially reopened in November 1953 with Lenin and Stalin side-by-side. Another plan decreed in March 1953, construction of the Pantheon to where the bodies of Lenin and Stalin would be eventually relocated, did not take off. Eight years later, removal of Stalin's body from the Mausoleum was unanimously sanctioned by the 22nd Congress of the Communist Party. On October 31, 1961, the Mausoleum was quickly covered with plywood. Red Square itself was routinely closed in preparation for the November 7th parade. Stalin's remains were quickly re-interred in a deep grave, lined with concrete blocks, behind the Mausoleum; the ceremony was attended only by the state commission led by Nikolay Shvernik. Harold Skilling, who attended the Mausoleum in November of the same year, noted that "everyone was so curious to see the new grave of Stalin... Unlike others, his [grave] was not yet graced by a bust and was marked only by a tablet with the name I.V.Stalin and dates of birth and death". The existing tomb of Stalin carved by Nikolai Tomsky was installed in June 1970.
