In addition to the objects of the architecture of the totalitarian regimes of 20th century, Tirana offers a couple of other such objects of both periods. The Palace of Brigades (former Palace of the Albania's King Zog I), the ministries buildings, the government building and the municipality hall are designed by Florestano Di Fausto and Armando Brasini, both well-known architects of the Mussolini period in Italy. The Dëshmorët e Kombit Boulevard was built in 1930 and given the name King Zog I Boulevard. In the communist period, the part from Skanderbeg Square up to the train station was named Stalin Boulevard. The Royal Palace or Palace of Brigades previously served as the official residence of King Zog I. It has been used by different Albanian governments for various purposes. Because of the outbreak of World War II, and the 1939 Italian invasion of Albania, King Zog I fled Albania and never had a chance to see the Palace fully constructed. The Italians finished it and used it as the Army Headquarters. The Palace took its nickname Palace of Brigades because it was taken from the Italians by a people army brigade.
