The archaeological features at Reeves Point, as the physical remains of the earliest formal European Settlement in South Australia, are of historical and social significance. The site is not only the place where the State of South Australia had its beginnings, founded by the South Australian Company according to the Wakefield Plan for Colonial Societies, but it also evokes a sense of past. The archaeological remains are a reminder of the failure in planning and misunderstanding of Australian conditions by those who conceived the Settlement in London. They are also a symbol of the struggle which early immigrants had, coming with high expectations to an unknown and seemingly hostile environment. The first site of South Australian Settlement in the Colony.
Reeves Point consists of a sloping headland and sand spit jutting into Nepean Bay. Clearly visible features include the mulberry tree, cemetery, the post-office cairn and a series of depressions on the hillside. Thirty-two Archaeological features have been recorded at the site, most thought to date from the South Australia Settlement from 1836 to 1848. The most visible of these features are cuttings and depressions in the ground, being the remains of cellars of some houses and a roadway. Other frequent features are alignments of stone and mortar, being foundation remains of other houses. Traces of the wooden piles of a jetty, possibly the second one built, are found at water's edge. Scatters of bottle glass, ceramic, bricks and other artefacts litter the beach having eroded out of rubbish heaps along the shore. The cemetery includes graves from the first Settlement as well as from their descendents.
The mulberry tree has survived from the first days of the Settlement.
