shack". The current parliament, a neoclassical three-floor structure designed by Friedrich von Gärtner and completed in 1843, originally served as a palace for the Greek monarchs, hence sometimes still referred to as the "Old Palace" (). After suffering fire damage in 1909, it entered a long period of renovation. The king and royal family moved to what was from 1897 until then the Crown Prince's Palace, from then on known as the "New Palace", one block to the east on Herodou Attikou Street, while some royals continued to reside in the "Old Palace" until 1924, when a referendum abolished the monarchy. The building was then used for many different purposes — functioning as a makeshift hospital, a museum, etc. — until November 1929, when government decided that the building would permanently house Parliament. After more extensive renovations, the Senate convened in the "Old Palace" () on 2 August 1934, followed by the Fifth National Assembly on 1 July 1935. Although the monarchy was restored that same year, the building has housed Parliament ever since. The Tomb of the Unknown Soldier (), guarded round the clock by the Evzones of the Presidential Guard, is located in the formal forecourt of the building. Construction of the monument began in 1929, and it was inaugurated on March 25, 1932. The main chamber of parliament, on the ground floor, is amphitheatrical in layout, and is panelled in purple and purple-veined white marble, with inlaid gold ornaments. Seating for the MPs is arranged in five circular sectors. The speaker's chair, the lectern, the ministerial and state functionary benches, and the shorthand's vault are made of carved wood and are laid out facing the MP seats. A colonnaded balcony surrounds the upper tier of the chamber and is used as the visitors' gallery. Part of it served as the royal box in the past. A vitrail roof provides natural light during daytime. An almost identical (but smaller-scaled) chamber was built in the second floor for use of the senate. Since there has not been a senate for several decades, this chamber has no official function any more, and is used for party caucuses and other parliamentary or party functions on an ad hoc basis. The building has two main entrances: the west-facing formal entrance (facing the Tomb of the Unknown Soldier and Syntagma Square) and the east-facing business entrance (facing the National Gardens). Improvements are ongoing
