use of building elements to reinforce the memorial's purpose. When lowered (normally between 9am and 5pm) they are virtually invisible and allow unobstructed public access. The great doors and windows There are ten sets of great doors to the building, seven on the ground floor and three on the podium level. All the doors are double leaf sliding doors of solid silky oak timber with brass furniture. The sets of external doors are painted green externally and gold internally. The doors slide on tracks that are recessed in the masonry walls of the building. The sets of doors are all panelled and decorated with carvings of urns, eternals flames, swords and crosses all symbolic of the memorial. These doors were repaired and repainted in 2006. Moveable heritage There is an extensive collection of artefacts, items of memorabilia and tributes on display in the Museum space or stored in a number of small spaces on site, including one of the safes. These items have all been donated by members of the public. Mechanical and electrical services Construction works during 2009 upgraded the services in the building, including the air-conditioning with the installation of new suspended services spine for ductwork, lighting and security services through the exhibition area and offices. Many of the original electrical fittings remain in use in the building. These include switches and lighting. The original star lights, designed by Dellit and inspired by the stars on the ceiling of the Hall of Memories, are still used throughout the building. The original wall bracket light fittings in the Assembly Hall are also still used. Condition As at 26 February 2010, following many years of major catch-up maintenance and repair works, the general condition of the Memorial in 2010 is very good. Water ingress has been a constant issue within the building since it opened in 1934. In 2009 this was resolved with modifications to the podium drainage and paving system. Archaeology The archaeological potential of the site has not been formally assessed. Hyde Park was the site of Australia's first race course and cricket pitch. Recent scholarship suggests Hyde Park north was also the site of a "fighting ground" for staging combative trials, first by the Aboriginal people between their own clans, later by Aboriginal people in demonstrating their fighting prowess against the British. Evidence associated with these uses as well as former park layouts may still exist within
