Casa Abaroa, Historical museum in Antofagasta, Chile

Casa Abaroa is a French neoclassical house featuring two main floors, a basement level, and graceful arched windows throughout. The building showcases ornamental balustrades along its main corridor stairs and reflects the architectural style of wealthy residences in early 20th century Chile.

The house was built in 1920 by Jaime Pedreny for Bolivian businessman Andrónico Abaroa Rivero, son of Eduardo Abaroa Hidalgo, hero of the Battle of Topáter. It was declared a National Historic Monument on 6 February 2008 by decree No. 465. In 2002 the Regional Council of Antofagasta had already listed it as a Historic Conservation Property.

The house served as a space where the nitrate industry's story and regional development were presented to visitors. People came here to learn about the entrepreneurs who shaped the northern city and their legacy.

The building is located near Parque Brasil and is easy to reach when exploring that part of the city. It offers access to multiple levels, so wearing comfortable shoes and allowing time to explore the different floors would be helpful.

The house had two entrances: a main one in the east wing and a service entrance that connected to the Antofagasta coastal road. The main staircase runs parallel to the front door, and the large hipped roof carries a double dormer window.
