Bosch Palace, Neoclassical diplomatic residence in Palermo, Buenos Aires, Argentina

Bosch Palace is a French Neoclassical mansion on Avenida del Libertador, overlooking Parque Tres de Febrero in Palermo. French architect René Sergent designed it in 1912 for Ernesto Bosch, and Argentine architects Lanús and Hary oversaw construction, completed in 1917. The 3,700 m² residence has facades clad in stone-like material, while its interiors were fitted with materials and furniture imported from France.

The building was constructed in 1917 as a private residence for Argentine diplomat Ernesto Bosch and took his name. In 1929 the United States government acquired it and established it as the official residence of its ambassador.

The house was built to recall the Bosches' years in Paris, and its interiors were fitted with materials and furniture imported from France. The name Palacio Bosch-Alvear links the family to Alvear Avenue, near whose northern end the mansion was built. Since 1929 it has served as the residence of the U.S. ambassador, and presidents Franklin Roosevelt (1936), Dwight Eisenhower (1960), George H. W. Bush (1994) and Barack Obama (2016) stayed here.

The building functions as an official residence and is not regularly open for public tours. Visitors can admire the exterior facade and garden landscaping from the street without access to the interior.

The 3,700 m² mansion was completed in 1917. U.S. Ambassador Robert Woods Bliss first showed interest during a reception held there in his honor; Bosch, unwilling to sell, named an absurdly high price, and when the ambassador returned days later with his government's acceptance, Bosch felt obliged to sell for around US$3 million in 1929.
