Located on the south side of the Plaza de Cagancha in Montevideo, on the Human Rights Passage, it was declared a National Historical Monument in 1975.

In front of its main entrance is the Monument to Justice, a work by Rafael Lorente Mourelle.

The construction of the building was projected by the Uruguayan businessman and philanthropist Francisco Piria in 1917 as a family residence.

The design was carried out by the French architect Camille Gardelle, a former student of the Beaux-Arts de Paris.

12,090, the Palacio Piria was acquired by the Uruguayan State, and destined to house the Supreme Court of Justice.
