St. Joseph's Cathedral faces Plaza Colón in the centre of Antofagasta and serves as the seat of the Roman Catholic Archdiocese of Antofagasta. The building was constructed in 1917 in a colonial-influenced style, with a pale stone facade that stands out against the dry coastal surroundings.
The interior is relatively simple but well maintained, with colourful stained glass windows and carved wooden pews. Like much of Antofagasta's historic centre, the cathedral reflects the city's origins as a company town built during the nitrate and copper booms, when both British and Chilean communities constructed their respective institutions within a few blocks of each other. It is worth a short visit if you are walking the central plaza area.
Address: Plaza Colón, Antofagasta.
