During the construction of the Royal Palace, the Yugoslav King Alexander I wanted to build a house for his children, so the White Palace came into existence. After the assassination of King Alexander I in 1934 in Marseille, Queen Mary and the prince’s children, including the young King Peter II, who was 11 years old, stayed at the Royal Palace and the New Palace in downtown Belgrade, which became the family’s official residence. later the seat of the Serbian presidency. The construction of the White Palace continued until 1936, when the works were completed. It then became the residence of Prince Regent Paul of Yugoslavia and his family until King Peter II came of age.

The exterior walls are plastered in white, while the decorations of the windows, cornices and pillars in stone are always white, which is why the building got its name. The main façade has a flat central structure with two protruding side masses. The atrium is preceded by a portico with pillars reminiscent of the Doric style, which support the terrace overlooking the windows on the second floor. There are three entrance doors and they all have glass panes: they are separated by pilasters with capitals of the same style as the pillars. On the second floor, three central windows have a decoration that ends in a triangular moulding, and are flanked by ionic pilasters that support the gable at the top of the facade, above three small windows on the third floor. The windows on the first floor of the two side bodies are three-part: the central one is higher and ends with an arch.
