[2][3][4] Built in the late Italian Baroque style with neoclassical features, the temple has a Greek cross floor plan, a rectangular chancel and a central dome.

The original project did not foresee any towers on the facade, which is now divided into three sections delimited by columns and pilasters; an entablature separates the two storey levels.

[2][3][4] In 2004, the National Institute of Historic and Artistic Heritage (Instituto do Patrimônio Histórico e Artístico Nacional - IPHAN) began restoration work on the church.

In 2005, the Brazilian Development Bank (Banco Nacional do Desenvolvimento - BNDES) complemented IPHAN's renovation by supporting the execution of architectural services and the artistic restoration of movable and integrated elements.

The temple's rear and left side facades were also restored, with pilasters, architrave and openings rebuilt from the remains found in the walls.
