Población Los Castaños, Residential complex in Independencia, Chile.

Población Los Castaños is a residential complex in Independencia with 84 houses built in the Art Nouveau style that line Avenida Francia. The homes feature individual front yards and facades with ornamental details, with living spaces ranging from 54 to 270 square meters.

Luciano Kulczewski designed the complex in 1930 for the Caja de Asistencia, Prevención y Bienestar de la Policía, which built 84 dwellings for Santiago's middle class on former farmland. It was declared a National Monument in the Typical Zone category by Decree No. 285 of 20 May 1996. Two other Kulczewski housing groups, Virginia Opazo (1930) and Calle Keller (1925), also hold that designation.

The neighborhood displays ornamental details such as animal figures, urns, and floral patterns that shape daily life for residents. These decorative elements came from Luciano Kulczewski, a Polish-Chilean architect who gave each house its own character.

The neighborhood is best explored on foot, with the continuous arrangement of homes making it easy to walk between the front yards. Access is straightforward and there is no admission, since this is an inhabited residential area.

The 1996 Typical Zone designation, by Decree No. 285 of 20 May, covers the whole complex rather than a single house. Two other Kulczewski housing groups share this status: the Virginia Opazo complex (1930) in Santiago commune and the Keller street complex (1925) in Providencia.
