The Parliament is one of the symbols of the capital and the country. The building, along with the Danube and the Castle District, is part of the UNESCO World Heritage Site. Half of the building serves as a visitor centre, and the other half houses the legislative functions. It was constructed at the end of the 19th century in neo-gothic, baroque, and renaissance styles by designer Imre Steindl. The Hungarian Parliament is the second largest in Europe, standing 96 metres tall, which is the same height as St Stephen's Basilica. This height symbolizes the equality between the State and the Church and references the year 896 when the 7 nomadic tribes arrived in the Carpathian Basin. The building, stretching 268 metres long, houses the Holy Crown and the coronation insignia including the scepter, the sword, and the national apple. Constructed on the Pest side, opposite the Buda Castle, the building's location symbolizes the unity of the two cities, which merged in 1873 with Óbuda to form Budapest. The Parliament building has been damaged several times throughout history, particularly during the Second World War and the 1956 revolution. Kossuth Square, where the Parliament is located, is a significant historical and political site that hosts various events. Visitors can explore the building through guided tours available in several languages and can visit its museum and library which cover an area of 1,700 square metres. Each year, around seven hundred thousand people visit the Parliament, making it a must-see attraction in Hungary.
