The peace and tranquility of Hampstead Heath are enjoyed by millions every year.
Now campaigners argue that the very things which make Hampstead Heath so appealing could be destroyed by planned works to improve flood defences around its legendary ponds.
The City Of London Corporation, who manage the Heath, insist works to create natural dams are essential to prevent danger to residences nearby if a serious flood hit the area.
Their sentiments are not popular. Swimmers, fishing clubs and other local residents have grouped together to take the Corporation to the High Court, arguing that these works will destroy its unique character and charm for up to two years. They argue the flood defences are unnecessarily ardent.
A two day hearing at the Royal Courts of Justice, starting on Thursday 13th November, will examine both sides' arguments in detail.
It is hoped a decision on whether planned works can go ahead may be reached by the end of this year.
