The Parliament Building was constructed at a time when Hungary was three times the size it is now, prior to its defeat at the culmination of World War I. The neo-Gothic building is a palatial affair with 691 rooms, 10 courtyards and 20 kilometers (12.5 miles) worth of stairs; it is Budapest's tallest building and one of Hungary's largest structures. Construction began in 1885 upon the designs of architect, Imre Steindl, and would take 17 years to bring to fruition; a majestic Gothic Revival building with Renaissance and Baroque elements enmeshed in its intricate design. A lavish dome is the centerpiece of the facade, framed by delicate spires and graceful arches, while the interiors are richly ornamented, illuminated by sparkling chandeliers. The inspiration for this building is said to have been the Palace of Westminster in London. Today, the government is housed in only a small portion of the building and is home to the Hungarian Crown Jewels. Like so much along the Pest bank of the Danube, the best views are to be had from across the river. Guided tours are available when parliament is not in session.
