Situated on Rua Sá da Bandeira, at the bottom of Avenida dos Aliados is this interesting church. Igreja de Santo António dos Congregados.
Dating back to 1703 it was built on the site of a smaller 17th century chapel. Besides its attractive facade, the church's main claim to fame is that it is said to house part of the body of Pope Saint Clement I who was martyred in the 1st century.
