Lenin's Mausoleum, Red Square: 92 years and counting this week.  This is his second mausoleum, the first one having been built of wood; he has been in this one since August 1924.  The mausoleum is incidentally a UNESCO World Heritage site, being part of the greater Red Square complex. He'd freak out if he were to get up and witness the capitalist activity that now surrounds him.
