Special gardeners of Kumsusan Palace in Pyongyang
Tweezers and brushes are key tools as devoted crew ensure not a blade of grass is out of place

At first glance it seems like a task worthy of Hercules, manicuring lawns the size of a football field with a pair of tweezers.
These are not just any lawns. These make up the gardens of one of the most sacred sites in North Korea, the Kumsusan Palace of the Sun in Pyongyang, in which lie the embalmed bodies of the nation's founder Kim Il-sung and his son and successor Kim Jong-il.
So the gardening duties come with added pressure.
For a country of severe winters, the lawns are in impressive shape, covered in thick, healthy, bright green grass that both enhances and softens the visual impact of the monumental mausoleum.
During the day, a small brigade of men and women are seen squatting in various sections, plucking furiously at patches of turf with tools that would seem better equipped for pruning a bonsai than tending a meadow.
