The mace took 300 hours to craft and is made from gold, silver and brass. In 2006, it was worth around £10,500 (A$25,000) and was handed over to the National Assembly during the opening ceremony. All committee meetings are held in three committee rooms. Each can accommodate 24 people, although committee rooms 1 and 2 can both hold 34 when fully opened. Members of the public can access the committee room viewing galleries from the Neuadd, which holds 31 people. Members of the public enter the building through Y Neuadd ("The Hall" ). This first floor level houses the public reception and information area. The reception desk features a large slate and glass desk and a canopy. Stairs to the left of the desk lead to the Oriel on the second floor. Yr Oriel ("The Gallery", from ; ) is a public sitting and exhibition area with views down to Y Siambr and committee rooms. The glass flooring, which surrounds a large funnel feature, enables visitors to look down into the Siambr two floors below. The Swan chairs selected for the Neuadd and Oriel areas were from Fritz Hansen, a Danish company, and originally designed by Arne Jacobsen in 1958. "Y Cwrt" ("The Courtyard"; ) is an area on the ground floor with a members' tea room, a media briefing room, and access to the Siambr and committee rooms. It is accessible only to AMs, officials of the National Assembly and members of the press. An undulating ceiling made of Canadian-sourced Western Redcedar timber spans across the various sections of the building. It was manufactured and installed by BCL Timber Projects (sub-contracted by Taylor Woodrow). Four pieces of art were commissioned by the National Assembly to be both decorative and functional; they cost £300,000 in total. The Swansea based artist Alexander Beleschenko designed and created the circular and domed "Heart of Wales" for the centre of the "Siambr". It is wide, made out of blue and gold glass, and lit from beneath. Martin Richman designed and created 270 fabric-covered acoustic absorption panels, which were dyed and painted. American sculptor Danny Lane designed and created the wind hedge, "Assembly Field". It has five parallel rows of 32 glass plates and was designed to have the practical use of protecting the public from high winds coming off Cardiff Bay. Devon born sculptor Richard Harris created "The Meeting Place on the Plinth", which is 45 tonnes of slate machine-cut into 39 slate slabs; the slate was from Cwt y Bugail Quarry in north Wales.
