Construction started during the second government of Augusto B. Leguía (1919–1930) and finished under the presidency of Óscar R. Benavides, who inaugurated the building in the late 1930s. The Palace was built in a neoclassical style as its plans were based on those of the Law Courts of Brussels, Belgium, work of Joseph Poelaert.
