The Budapest Parliament building is the third largest Parliament building in the world. It has 691 rooms, 20 kilometers (12,5 miles) of stairs and at 96 meters (315 feet) it is the same height as the St. Stephen's Basilica.

Guided tours of the Parliament are available when the National Assembly is not in session. The tour takes about 45 minutes, and is well worth the price, as it covers the main entrance stairs and hall, one of the lobbies, the old House of Lords and the Hungarian Crown Jewels. Tours are held in several languages.
