Palacio Subercaseaux, Historical monument near Plaza del Teatro Municipal, Santiago, Chile

Palacio Subercaseaux is a continuous-facade building of masonry on Agustinas street, between San Antonio and Enrique Mac-Iver, facing Pasaje Tenderini. It has two floors plus a basement level and a mansard roof, inspired by Louis XV and Louis XVI styles. Its double-height main hall holds a parquet floor, wall sconces and a white Carrara marble staircase.

Francisco Subercaseaux Vicuña first commissioned two palaces for his sons from architect Miguel Ángel de la Cruz Labarca, who had studied in Paris. After seeing them finished, he ordered this third palace for himself and his wife Juana Brown; construction began in 1903. Alberto Cruz Montt handled the interior finishes and Julio Montt altered the room layout. Before 1921 one balcony door was converted into an independent entrance. On 7 April 1951 the building became the Chilean Air Force Officers Club, and in February 1973 it was declared a National Monument.

Rooms on the first floor carry names of Chilean Air Force figures, such as the Salón General Diego Aracena Aguilar, also called Salón Francés, and the Salón Capitán Dagoberto Godoy, known as Salón del Piano. Juana Brown, a noted pianist, asked for a music room facing the Teatro Municipal. The main hall has a Carrara marble staircase and parquet flooring.

The palace now serves as an officers club headquarters and is typically accessible to visitors with authorization or on scheduled tours. It is recommended to obtain advance information about opening times and access requirements.

Juana Brown asked for a music room facing the Teatro Municipal, across the street, to recall a trip to Paris she had made with her husband years earlier. The palace's rooms are named after figures of the Chilean Air Force, such as General Diego Aracena Aguilar and Captain Dagoberto Godoy.
