Casona Ochagavía

Casona Ochagavía is a manor house in Pedro Aguirre Cerda organized around a central courtyard lined with wooden-pillar corridors that extends across two stories. The surrounding rooms show the residential areas, storage spaces, and service quarters of the original estate.

The manor was built between 1760 and 1770 and later served as a strategic base for the patriot army before the Battle of Maipú in 1818. It played an important role in Chile's independence campaign.

The building shows the traditional construction methods of 19th-century Chilean manor houses with walls made from clay and straw mixtures. The architecture reveals the everyday living spaces of a wealthy family from that era.

The property is managed today by the municipality of Pedro Aguirre Cerda and remains accessible to visitors. Extensive restoration work was completed following the 2010 earthquake to preserve the building.

A large eucalyptus tree stands in the grounds with a trunk several meters wide, its presence connecting the space to the era of the independence wars. The tree's age reflects the long history of this location.
