[2] A commission, which consisted of an engineer, bricklayer, and carpenter, surveyed the building in 1754 and found the construction of the church to be satisfactory, but at a cost that exceeded the donation of the crown.

Francisco Amorim da Silva's request for reimbursement by the Treasury was granted in the same year, implying that construction of the church was completed per instructions of the Portuguese colonial government.

[1] The Mother Church of Our Lady of the Rosary forms a small block between Ana Nery Street and 13 de Maio Square in the lower part of the city.

The church tower provides a view of the city of Cachoeira and parts of São Felix, which is located on opposite bank of the Paraguaçu River.

[2] The frontispiece is flanked by two towers with pyramidal towers; they are glazed in tile in a distinctive zig-zag pattern, an element common to the Seminary of Belém, also in Cachoeira; the churches of Boa Viagem and Santa Casa de Misericórdia both in Salvador, and the Convent of Saint Antonio in the municipality of São Francisco do Conde.

[1][2] The ceiling of the nave is of wood and painted in the Italian trompe-l'œil illusionist style; they were executed by José Joaquim da Rocha.
