Since the moment it opened in 1908, the Teatro Colón has hosted Argentina’s crème de la crème as well as top musicians and composers from around the world, among them Igor Stravinsky, local tango legend Astor Piazzolla, and Luciano Pavarotti. During a $340 million renovation that lasted from 2006 to 2010, the auditorium’s perfect acoustics were painstakingly preserved. Guided tours every 15 minutes offer up-close views of the building’s magnificent features, including a five-ton crystal chandelier. But to really experience all the drama and grandeur, snag a ticket to the ballet, opera, or a concert. There are several shows a week, typically featuring performers of international renown.
