The garden (originally intended as one circular space with the North side garden) was created during the development boom of the 1820s. The simple design was to have the space laid out in a complementary manner with an outer belt of trees and shrubs with a gravel path running alongside. The interior was grassed and planted with specimen trees with an entrance at the centre of the crescent. The Second World War saw the removal of the railings, and the garden requisitioned to provide space for two air raid shelters. New railings were added in 1992.
