The Old Palace is a historic building in the city of Belgrade, capital of Serbia, and is the seat of the town assembly. Acquired Autonomy by the Ottoman Empire, Serbia was organized in principality. The first sovereign recognized by the Turkish authorities, Milos Obrenovic, is supposed to have lived at some of the pre-existing buildings in the center of Belgrade, until he built two official residences between 1831 and 1834, the first for himself and the courtyard, in the area of the park of Topčider, far away from the headquarters of the Ottoman garrison located in the fortress of Kalemegdan, the other, for his wife, the prince Ljubica, and the sons of Milan and Mihailo inside the wall boundary. Between 1839 and 1878 the Serbian throne passed by six times, and the country lived for forty years of instability until Prince Milan IV was appointed. It was he who, after recognizing the independence of Serbia from Turkey, decided to give the monarchy an official residence that surpassed the buildings in the city and was the official residence of the Obrenović family. For the construction of the palace, Milan chose a marshy land outside the center of the city, which the state had bought from businessman Stojan Simić; He also intends to build the court's office. In 1882, the prince proclaimed king, assuming the name of Milan I, and took possession of the palace in 1884 when its construction was completed. On May 6, 1889, Milan I abdicated and passed the crown to his son Alessandro primo who on June 11, 1903 was a victim of a coup d'état: the insurgents surrounded the royal palace and killed the king and queen. The plan of the palace is square and the sides have a length of 40 meters. The façades are all different and the southern one, overlooking the garden, is the most decorated. It has three registers: the lower one has a white marble socket overhanged by a wall decorated with trellis, with small windows framed by a smooth molding. The middle register has, for the whole length, a terracing delimited by a marble balustrade. The eastern façade, destroyed in 1941, was rebuilt as a single body where the movement is given by the pronaos, topped by a terrace supported by Doric columns, which embellishes the entrance, and the wall of the upper register slightly backward. The windows are framed by very simple moldings. The English writer Herbert Vivien, who visited the palace at the end of the nineteenth century, described his interior in detail: "On the left side there is a beautiful ballroom with walls of yellow lemon, illuminated by Venetian windows, which shine during parties, even in the presence of electric light. The Bulgarian architect had built a covered structure in the center of the building, which served as a winter garden, from which galleries were given, giving access to the exhibition halls; there was an Orthodox chapel and a library with a large collection of volumes. From the "red salon" there is access to the "yellow salon" which houses numerous paintings by Yugoslav authors and various porcelain items on the walls, a gift from foreign delegations visiting Belgrade. From the yellow salon passes to the gala salon measuring 260 square meters, and has a double height compared to the others; this environment features, at the top, worked glass windows depicting the struggle for liberation of the people and the enthusiasm of work. The "19th Century Salon" was furnished by the Museum of the City of Belgrade with furniture and furnishings typical of that period. Many pieces are the original ones used by King Milan's wife, Queen Natalia, and mostly belong to Louis XV, Napoleon III and Biedermeier styles.
