Igreja de Santo António
This early-18th-century baroque building is Lagos's most extraordinary structure. Its interior is a riot of gilt extravagance made possible by the import of gold from Brazil. Dozens of cherubs and angels clamber over the walls, among fancifully carved woodwork and azulejos. In an annexe is the Museu Municipal Dr. José Formosinho, with a range of 18th-century artworks and archaeological findings.
