Casa Chadwick, Neoclassical house in La Serena, Chile.

Casa Chadwick is a two-story adobe house in La Serena built in the neoclassical style. Its lower level has wooden decorations and windows with wrought-iron grilles, while the upper floor has doors, windows and iron balconies bearing republican shields. A turned-wood false balcony and two interior patios complete the structure.

Casa Chadwick was built between 1865 and 1870 by Bartolo Varela as the residence of the Varela Pérez family, in a La Serena transformed by the 1825 discovery of the Arqueros silver mine. José Chadwick Valdés carried out its conservation, and the house takes its name from him. It was declared a National Historic Monument on 12 February 1981 by Supreme Decree No. 499; the Instituto Profesional de Chile now occupies it.

The house keeps its original name from the Varela Pérez family, for whom Bartolo Varela built it, and the Chadwick name comes from José Chadwick Valdés, who carried out its conservation. On special occasions the rooms host recreations in period dress and typical clothing of the era.

The house sits at Los Carreras 281 in La Serena's historic center within walking distance of other period buildings and plazas. Visitors can view the exterior facade and may see portions of the courtyards depending on current access and the building's active use.

The house keeps its original layout: two interior courtyards, a lower level with carved wooden decoration and barred windows, and an upper floor with iron balconies bearing republican shields. On special occasions, participants dress in period clothing for re-enactments of life in the Casa Chadwick.
