groups within NSW society including present and former residents of The Rocks and Millers Point; people involved in the fight to save the Rocks in the 1970s; descendants of the many artillerymen and their families who were stationed at Dawes Point; and Bridge construction and maintenance workers, their families and descendants. Dawes Point, as a setting for the Harbour Bridge, is valued for its aesthetic and engineering significance by several identifiable groups including the Institution of Engineers (Australia) and the Royal Australian Institute of Architects 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 excavation, conservation and interpretation of the Dawes Point Battery remains has won several prestigious awards since 2001, indicating the historical, social, technical and research significance the place holds, not only for the public, but also for professional bodies. Dawes Point Battery remains was listed on the New South Wales State Heritage Register on 10 May 2002 having satisfied the following criteria.
