Igreja de Nossa Senhora das Mercês e Misericórdia, Colonial church in Ouro Preto, Brazil.

Igreja de Nossa Senhora das Mercês e Misericórdia is a church located in Ouro Preto with a central tower and a soapstone entrance portico decorated with a triangular pediment and carved ornaments. The building occupies a prominent site and features a surrounding stone wall that defines its grounds.

Construction of the church started in 1771 under master builder Manuel Francisco de Araújo, who shaped its initial design. The central tower was added around 1840, completing the structure as it appears today.

The soapstone medallion on the portico, carved in 1810, shows the Virgin with open arms spreading her mantle over captives of the Moors, following the dream of the founder of the Mercedarian Order. It was once attributed to Aleijadinho. The brotherhood, founded in Vila Rica around 1740–1754, split into two groups, and this one built its own seat from 1771.

The church stands high on the Ouro Preto hillside, so the approach is uphill and the street is steep; the building is a reference point for anyone arriving in or leaving the city. Its position near the site of the old garrison barracks, later replaced by a public school, explains the military invocation of the brotherhood.

The single central tower, added in the 19th century, departs from the two-tower layout usual in Ouro Preto churches; Paulo Ferreira Santos described it as an evolved type of chapel built on wooden posts. The soapstone medallion over the entrance, carved in 1810, shows the Virgin opening her mantle over captive Moors, following the founder's dream, and was once attributed to Aleijadinho.
