Located behind Porto's City Hall, this 19th-century church is a gem of Neoclassical style. Even though it is not a popular tourist attraction, it is definitely worth visiting for its interior decorations including sculptures and exquisite woodwork. Due to its acoustics, many concerts take place here throughout the year.
