Jewel House (home of the Crown Jewels)
No, not those crown jewels – although you might want to be careful if you’re photographing those as well. No-one is allowed to take pictures of this breathtaking array of jewels, which are protected by bombproof glass at the Tower of London. All visitors are watched by a beady-eyed array of guards and more than 100 security cameras, so don’t get any funny ideas.
Kumsusan Palace of the Sun
Pyongyang, North Korea
Before entering the mausoleum of Kim Il-sung and Kim Jong-il, visitors must check-in all their belongings apart from their wallet. They must then walk through a dust-blowing machine to ensure no dust is carried into the room where the former heads of state lie in their transparent crystal sarcophagi. Photography definitely isn’t allowed.
