Convent and Church of Saint Antony, Baroque convent and church in Cachoeira, Brazil.

The Convent and Church of Saint Antony is a two-story complex of mixed masonry with a church, convent, and a multi-level garden leading down to a stone quay on the Iguape. The church frontispiece faces the river with a five-arch gallery and five choir windows; its rococo pediments show Chinese-influenced elements. A large cross on a polyhedron sandstone pedestal stands in the garden, and the kitchen's conical chimney remains.

Construction of the complex began in 1658, with the church consecrated in 1660 and the entire ensemble completed around 1686. These dates mark the early establishment of Baroque architecture in South America during the colonial period.

The complex displays early Brazilian Baroque style that became a model for churches throughout northeastern Brazil. This architectural approach developed here before it reached Portugal, making the site an important point of origin for this design tradition.

The complex stands on a slight embankment above the Iguape estuary of the Paraguaçu River, far from Cachoeira's city centre; roads to the Iguape community were built only later, and a stone quay on the river is still active. A multi-level garden with volute-decorated walls climbs from the quay to the church entrance, and one convent wing reaches out to the water.

By 1857 the convent population had shrunk to just five residents, and the complex was abandoned in the early 1900s. Most interior furnishings were removed, yet the external structures survived this period of neglect.
