The seat of Australia's federal government and legislature and a remarkable piece of modern architecture. Outside, the forecourt faces Federation Mall and has iconic views. Much of the inside is open to the public during business hours (your bags are x-rayed and persons pass through a metal detector at the entrance). When inside the building, do not miss: Queens Terrace upstairs towards the forecourt, and the roof (via an elevator close to walkway to the House of Representatives). Various art, including portraits of past prime ministers are hung in the hallways. Enthusiastic guides perform free tours daily at 10AM, 1PM and 3PM (no booking required). Tours are shorter when Parliament is sitting as the chambers are occupied.
