of the Anzac Memorial. The extension was the “centrepiece of the State's Centenary of Anzac commemorations, marking the 100th anniversary of the ending of the First World War”. The major extension realised architect Bruce Dellit's original concept for the Memorial and added new underground exhibition and education spaces. Premier Mike Baird said "by enhancing this memorial we are ensuring future generations can continue to honour those who fought for the freedoms we enjoy today". Construction was completed by Built and jointly funded by the NSW and Australian Governments. The upgrades included: A large water cascade feature on the southern side of the memorial, with new entrance and walkway. The Hall of Service: including “a major artwork by Fiona Hall featuring 1,701 soil samples from each NSW town, suburb and district given as the home address by First World War enlistees”. The Oculus, which is centred above the Hall of Service with a view out to the Memorial exterior. The extension was designed by JPW Architects and officially opened on 20 October 2018. Description The building is constructed of concrete, with an exterior cladding of pink granite, and consists of a massed square superstructure with typically Art Deco setbacks and buttresses, punctuated on each side by a large arched window of yellow stained glass, and crowned with a ziggurat-inspired stepped roof. It is positioned atop a cruciform pedestal within which are located administrative offices and a small museum. The interior is largely faced in white marble, and features a domed ceiling adorned with 120,000 gold stars – one for each of those men and women from New South Wales who served during World War I. Access to the main hall is provided via broad stairways on each side of the building's north–south axis, while ground-level doorways on the east and west sides offer entry to the lower section. The main focus of the interior is Rayner Hoff's monumental bronze sculpture of a deceased youth, representing a soldier, held aloft on his shield by a caryatid – three female figures, representing his mother, sister and wife. The male figure's nudity was considered shocking at the time of the monument's opening, and it is said to be the only such representation of a naked male form within any war memorial. Two other even more controversial figural sculptures designed by Hoff—one featuring a naked female figure—were never installed on the eastern and western faces
