Parish Church of Our Lady of the Rosary, Baroque Catholic church in Cachoeira, Brazil.

The Parish Church of Our Lady of the Rosary is a Baroque church in Cachoeira built with a rectangular floor plan and two side corridors. The structure features twin towers topped with pyramid shapes and load-bearing walls of stone and brick that form its solid frame.

Construction began in the late 17th century and continued into the following century, funded by local residents and the Portuguese Crown. King John V donated eight thousand cruzados for the main chapel, sacristy and the casa de fábrica of administrator Francisco Amorim da Silva. A commission of engineer, bricklayer and carpenter inspected the building in 1754 and approved it, and the church was completed that year. In 1842 it was the scene of bloody disputes over its administration.

The azulejos lining the interior, about 4 metres high, were installed between 1750 and 1760 and are considered the largest set of Portuguese tiles outside Portugal. They are typical of Lisbon production of the 1750s. The church is dedicated to Our Lady of the Rosary, and in 1842 it was the scene of bloody disputes between groups divided over its administration.

The building sits between Ana Nery Street and 13 de Maio Square in the lower section of Cachoeira's historic center. It is easy to reach on foot and located in an area you will naturally explore while walking through the old town.

The nave ceiling displays Italian illusionistic painting by José Joaquim da Rocha, a remarkable artistic achievement. The rococo side altars and neoclassical main altar create a visual interplay of different artistic styles across different periods.
