Casa Camus, Cultural heritage building in Antofagasta, Chile.

Casa Camus is a three-level building featuring Neoclassical architecture in downtown Antofagasta with symmetrical facades, classical columns, and balanced proportions. The structure combines European design principles with local construction methods adapted to the northern Chilean coastal environment.

Luis Camus, a mining entrepreneur, commissioned the house from Italo-Arab architect Luigi Abd-el-Kader, then in Buenos Aires; Spanish architect Jaime Pedreny built it in 1913 at Simón Bolívar and José Santos Ossa with Avenida Argentina. From the 1960s to the 1970s it housed a brothel, in the 1980s it served as the secret seat of the regional Communist Party committee, and later doctor Aldo Valenzuela turned it into his private practice. In 2002 architects Andrew Trench and Hans García rented part of it, bought it after Valenzuela's death in 2006 and restored it; that year the Consejo Regional declared it an Inmueble de Conservación Histórica.

The house is tied to a local legend about the ghostly appearance of a violinist, a story often repeated by residents. Between the 1960s and 1970s it operated as a brothel, and in the 1980s it served as the secret seat of the regional committee of the Communist Party. Since 2002 it has housed the architectural firm of Andrew Trench and Hans García.

Casa Camus stands at the corner of Simón Bolívar and José Santos Ossa streets with Avenida Argentina, in downtown Antofagasta. The architects Andrew Trench and Hans García bought the house in 2006 and restored it for their firm, so visits depend on the current occupants' arrangements. Antofagasta's desert coastal climate is mildest in the cooler months.

Casa Camus is linked to a local legend about the ghostly apparition of a violinist, a story often told alongside the building. Between 1960 and 1970 the house operated as a brothel, and in the 1980s it served as the secret seat of the regional committee of the Communist Party.
