UK farmer built illegal castle behind haybales

A farmer in the Green Belt outside London secretly built an elaborate castle without planning permission, hiding the work behind a wall of hay-bales. Now that the word has gotten out, they're going to knock it down:
A British farmer named Robert Fidler is fighting to keep the city from bulldozing his castle that he built by hiding the construction with hay bales. Officials were unaware of the elaborate castle because hundreds of bails of straw concealed it for four years, the UK Daily Telegraph reported Friday. After Fidler, 59 unveiled his home to neighbors in 2006 he was served a planning contravention notice the following March, which ordered demolition of the structure.
