Our Lady of Mercy Cathedral, Bahía Blanca

Our Lady of Mercy Cathedral is a Roman Catholic place of worship in Bahía Blanca featuring a balanced facade with two side towers that reach upward and a sculptural group at the center showing the Virgin Mary surrounded by angels. The building displays classical proportions with these towers as major design elements that frame the main entrance and give the structure its distinctive silhouette.

The original church structure was built in 1834 using materials typical of frontier settlements, including carob wood, adobe bricks, and straw to serve the early Catholic community. Over time it was replaced with the current stone cathedral that stands as a more permanent reflection of the growing city.

The cathedral houses the remains of Colonel Ramón Estomba, the founder of Bahía Blanca, connecting the religious structure to the city's origins. Visitors can see where this important local figure was laid to rest, making the space a point of connection between faith and civic history.

Mass services take place several times throughout the day, providing flexibility for visitors who wish to attend or simply experience the interior during worship. The building is generally open to the public outside of services, allowing people to enter and spend time in the space at their own pace.

Five bells cast by the Chiappani foundry in Trento, Italy, were installed in 1908 within one of the lateral towers, and their sound can still be heard across the city. These Italian-crafted bells represent a connection to European craftsmanship brought to the Argentine frontier.
