Cordoba/San Luis, Argentina

Córdoba, capital of the Argentine province of the same name, is known for its Spanish colonial architecture. It’s home to the Manzana Jesuítica (Jesuit Block), a 17th-century complex with active cloisters, churches and the original campus of the Universidad Nacional de Córdoba, one of South America’s oldest universities. The city’s focal point is Plaza San Martín and its neo-baroque Cathedral of Córdoba. San Luis is a town in central Argentina, in the Sierras Grandes mountains. Next to the leafy main square, Plaza Pringles, is a 19th-century cathedral, featuring a neoclassical facade and twin bell towers. Nearby, the Dora Ochoa De Masramón Provincial Museum exhibits a wide range of objects, from fossils and prehistoric remains to art and antiques. Tree-lined paths crisscross the expansive Park of Nations.
