I do not know how this abomination came about but I would suggest that someone needs to look at how they fulfil their role properly.
A giant doughnut-brandishing Homer Simpson has been painted onto the hillside above Cerne Abbas next to the giant. Apparently this is a publicity stunt to promote the Simpsons movie which is due to be released later this month.
Either the people who did this got permission in which case I would suggest that whoever granted permission should take a step back and think about how best to protect our heritage or they did not in which case they need to be caught and prosecuted.
The Cerne Abbas giant is a hill figure of a giant naked man on a hillside near the village of Cerne Abbas to the north of Dorchester in Dorset, England. The 55 metre (180 feet) high, 51 metres (167 feet) wide figure is carved into the side of a steep hill and is best viewed from the opposite side of the valley or from the air. The carving is formed by a trench 30cm (1 foot) wide and about the same depth which has been cut through the grass and earth into the underlying chalk. In his right hand the giant holds a knobbed club 36.5 metres (120 feet) long.
