Duc Ba Cathedral is located on Han Thuyen Street, facing down Dong Khoi Street, District 1, Ho Chi Minh City. Completed in 1880, the cathedral was built in a Western architectural style, it has a uniquely Eastern aspect. It was the symbol of the Western style and the spiritual and cultural crucible of the French presence in the Orient at that time.
The cathedral comprises of two main central bays with two sidereal corridors, with tall pillars and light coming in through sets of high windows, and a semi-circular shrine. The style follows a Roman pattern, although the outside contains some modifications: the cathedral’s vaults are Gothic, and a modern steel skeleton supports the whole building.
The cathedral is a much smaller than those in France, but it was the largest in the French empire. The interior is very large: the principal shrine and two additional bays are 93m long, and reach 35m in width at one point. The semi-circular shrine at the rear seats a choir during services, and there are five chapels. The walls are made of Bien Hoa granite, combined with red tiles from Marseilles, all without coating. Red tiles from France were also used on the roofs, but they were later replaced with tiles of equal quality from Phu Huu. Natural light streams in through stained-glass windows which were made by the Lorin Company from the French town of Sartre.
