Our history began as the Antofagasta (Chili) and Bolivia Railway Company limited, incorporated in London in 1888. It raised money on the London Stock Exchange to build and operate a railway from Antofagasta, a port on the Pacific Coast of northern Chile, to La Paz, the capital of Bolivia.

During the 1980s Antofagasta diversified into mining and other sectors, following acquisition of control by the Luksic Group.
