A project has launched to resurrect the 18th century Kew Ha-Ha.
A ha-ha is a sunken or blind fence, deer wall, or foss which creates a vertical barrier while preserving an uninterrupted view of a landscape.
The name comes from viewers’ surprise when seeing it.
The area outside Old Deer Sports Ground is thought to have been built as part of a landscaping project for Queen Charlotte.
But, in its current state, it could be mistaken for a ditch on the side of the road filled with bricks and overgrown plants.
Habitats and Heritage, the Royal Botanic Gardens, and Old Deer Park have raised only £150 of their £45,000 target to resurrect it so far.
Their aim is to create a wildlife corridor along the ha-ha which could attract animals such as badgers and beetles.
