Mausoleum Of The First Qin Emperor, Qin Shi Huang, China
Located in Lintong District, Xi’an, Shaanxi (China), Qin Shi Huang’s tomb is a place where entry is forbidden. Even though discovered when the Terracotta army was unearthed in 1974, the tomb hasn’t been excavated yet. Opponents of excavation believe that current technology couldn’t preserve anything that the tomb holds, therefore access to it is forbidden.
