San Luis
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.
