Looking west along the Shrewsbury Walk ha-ha

A ha-ha, or sunken fence, allowed uninterupted views from within a pleasure ground to the wider landscape beyond. Weston Park's two pleasure grounds are bound in by ha-has - deep sunken walls which retain the pleasure ground behind the wall and which have - on the park-side, a gentle slope. The shallow nature of the rising ground meant that animals such as deer could not jump the wall into the pleasure ground but this type of boundary allowed the eye to travel into the distance without the visual parameter that a fence or wall might have caused.
