The 750-year history of the Castle District of Buda spans significant eras, alternating between periods of growth and ruin. Royal residences and state buildings rose from the ground, only to suffer severe damage in a succession of sieges, battles and dictatorships. Launched in 2014, the National Hauszmann Programme aims to restore the Castle District to the splendour it enjoyed in its the heyday at the turn of the 19th and 20th centuries. The programme was named after acclaimed Hungarian architect Alajos Hauszmann, who led the reconstruction of the Castle District during the most glorious period of the palaces of Castle Hill.
Before the Second World War, the Castle District was the residence of the Head of State, and also home to several ministries. However, the magnificent buildings were severely damaged during the siege of the city during the war. During the 1960s and 70s, several buildings were simply demolished or rebuilt, which took away the more or less unified architectural image of the Castle District.
