Palacio Astoreca, Santiago de Chile, Neoclassical mansion in Santiago, Chile.

Palacio Astoreca is a neoclassical mansion featuring a symmetrical two-story structure with a false mansard roof and ornate marble staircases with balustrades throughout. The interior combines traditional proportions with elegant finishes that appear in both public and private rooms.

Built in 1910, the mansion was designed by architect Alberto Cruz Montt for the Astoreca family, whose wealth came from the Chilean saltpeter industry. Its construction occurred during an economic boom when industrialists commissioned grand residences throughout the city.

The building now houses the Chilean Association of Accountants and displays portraits of former presidents throughout its rooms. These French-inspired design choices reflect the tastes of wealthy families during the early 20th century.

The palace stands on Calle Dieciocho, between Padre Felipe Gómez de Vidaurre and Padre Alonso de Ovalle, in central Santiago; the sources give no street number. Its main facade is set back from the street behind a front garden, with two entrances and gates at the ends of the property leading to a porch and the main door. The building is occupied by the Colegio de Contadores de Chile, so visits depend on the institution's opening.

The interior preserves original French marble fireplaces, bronze hanging lamps, and walnut-paneled walls in the presidential chamber. These carefully crafted elements showcase the quality of materials and workmanship from that era.
