Mawson had begun his career as a landscape architect designing gardens for country houses.
Work started in 1893; a great quantity of soil was brought to the site to lay out the park.
On rising land at the northern end, on a former spoil heap, is an extensive rockery constructed of Pulhamite, through which runs an ornamental cascade.
Between the bandstand and the pavilion, on either side of the central axis, are two terracotta circular basins with simple fountains.
