The hills which host the Adelaide Pavilion, the grottos, and the grove of trees on top were created from 70 000 cubic metres of soil, that was carted from other places within the Park Lands, where excavation works had been undertaken.
Similar landscaping work was being done at about the same time in Rymill Park and in Bonython Park. Excess soil from each of those sites was brought here to create this mound. At Rymill Park they were also excavating a rubbish dump off Bartels Road in the late 1950's.
The Veale Gardens mounds changed the previously flat landscape and provides the garden with its characteristic form.
