Museo de la Plata
The Museo de la Plata, located about an hour outside of Buenos Aires in the city of La Plata, is an imposing turn-of-the-century building flanked by two carved saber-toothed tigers (once an Argentine native species). Considered one of the finest museums in the nation, the 7,000-square-meter building features exhibits focusing on everything from mineralogy to native plant life. Among other things, you’ll find huge replicas of ancient sloths, the skull of a blue whale, and an inventory of foods that have fed native people here for thousands of years—everything from local fruits to South American algaes to mushrooms. Don’t miss the Egyptian room, which contains artefacts found by Argentine archaeologists in Sudan. It takes about an hour and a half to go through the museum’s 23 rooms. Tours are offered in Spanish, but you must reserve your spot in advance through the website.
