It was designed by Hungarian architect Imre Steindl and opened in 1902. It has been the largest building in Hungary since its completion. The Parliament Building is built in the Gothic Revival style; it has a symmetrical façade and a central dome. The dome is Renaissance Revival architecture. The parliament is also largely symmetrical from the inside, with two identical parliament halls on the opposing sides of the building. One of the two halls is still in use today for sessions of the Hungarian National Assembly, the other for ceremonies, conferences, and guided tours.
