The Kumsusan Palace of the Sun in South Korea is a building that serves as the mausoleum for Kim Il-sung, the founder of North Korea, and for his son Kim Jong-il. It is not easy to get inside: foreigners can get permission to get inside the palace only during the official governmental tour. And the few people who manage to get inside the palace have to follow several rules. For example, taking photos or videos, smoking, and speaking are prohibited in any area of the mausoleum. Besides, all the visitors have to go through a special machine that blows off any dust they may have on themselves.
