the site is the only example of the careful mining of stone from this period in Sydney. The archaeology of the Battery floor and underground magazines also reveals elements constructed under the direction of George Barney, one of Australia's most important Colonial Engineers in the mid 19th century, such as the 1850s gun emplacements. Together with the presence of the cannon from this time, the Battery is an important archive of military history. The archaeological remains also have a strong aesthetic appeal as evocative ruins of Australia's colonial past. The 1789 Foundation Stone (now with the Mitchell Collection in the NSW State Library) and the five 1850s cannon contribute strongly to the heritage significance of the Place, in addition to being significant in their own right. Dawes Point maintains vestiges of all periods of its occupation. The Point has been terraced and filled with each successive land use. All of these land uses have been closely linked with the site's unique position, occupying as it does a prominent headland with vistas up and down the harbour. Dawes Point Park still encompasses more than 90% of the area set aside for military purposes in the 18th century. Very little of this area has been alienated from public use, allowing the potential for interpretation of this period of the site's history in particular. The layers of history at Dawes Point have great potential to be used as a rich educational, cultural and tourism resource. The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales. The Dawes Point Battery Remains is a rare historical precinct that contains evidence and associations of over 200 years of European occupation and as a contact site between the Eora and European cultures. It spans occupation and activity that includes scientific, defence, engineering and social values for the length of European occupation on the site. It is a magnificent landscaped setting for the Sydney Harbour Bridge and holds evidence of the Bridge's construction. It is the first defence installation set up in Australia and has rare surviving examples of subterranean powder magazines.
