Punta Arenas,our last stop in Chile, was an affluent Belle Epoque city back in the 19^th century. Until the Panama Canal was completed, it was a transportation hub, and the robust Patagonian wool trade created wealth for many families.  The European style of the city is apparent in its center at the Plaza de Armas, and the architecture is stunning. We visited one of the mansions created during that time–the Palacio Sara Braun at the Plaza Muños Gamero.   At the main square, we stopped into the Cathedral, where the bishop was celebrating a special mass for the sailors who were in town—and there were lots of them.   South American naval academies from Chile, Argentina, Brazil, and Columbia were all in town on this day, midway through their around-the-world sailing voyage.   This elite group of young sailors were happy to welcome visitors, pose for pictures, and swap travel stories—great fun!
