Igreja Nossa Senhora do Rosário, Catholic church in central Porto Alegre, Brazil

Igreja Nossa Senhora do Rosário is a Catholic church in downtown Porto Alegre that combines a contemporary structure with historical religious objects. The interior features a painting of the Battle of Lepanto in the main nave and preserves the original statue of Our Lady of the Rosary.

The original church was established in 1817, but the current building dates to 1956 following the demolition of the historic structure in 1951. This reconstruction reflected Porto Alegre's postwar religious modernization efforts.

The Rosary Brotherhood, established by enslaved and freed Black people, shaped how this place was used and understood as a community space. Their presence remains visible in the way the church functions within the neighborhood today.

The church is located in the downtown area and is easy to reach on foot from main streets. Visitors should know that it functions as an active place of worship with schedules that may vary according to religious services.

The 1956 church was built after the 1951 demolition of the original 1817 structure, which was de-listed with the authorization of President Getúlio Vargas. The new facade is clad in stone and has a mosaic of the patroness above the portico.
