Is it wrong to break into a national monument and then proceed to repair it?!
The Guardian Online has a great story about this happening. My favourite paragraph is:
Guardian Online wrote:Klausmann and his crew are connaisseurs of the Parisian underworld. Since the 1990s they have restored crypts, staged readings and plays in monuments at night, and organised rock concerts in quarries. The network was unknown to the authorities until 2004, when the police discovered an underground cinema, complete with bar and restaurant, under the Seine. They have tried to track them down ever since.
There are only 150 members in the whole world and have a cell dedicated to 'obtaining entrance to buildings at night' ie 'breaking and entering'. They are like the robin hoods of the modern generation! :D
