One of Mexico City's newest architectural icons opened in 2011 and includes one of the most valuable collections of art in Latin America. The largest number of works on display at this, the museum's Plaza Carso branch just beyond the edge of the popular Polanco neighborhood, come from the eclectic, 66,000-piece collection of billionaire philanthropist Carlos Slim Helu (one of the richest men in the world), which includes many sculptures from Rodin and Dalí, the largest such collection in Latin America, as well as numerous paintings from old masters to modernists and impressionists, including works from the circle of Leonardo da Vinci, El Greco, Tintoretto, Monet, and Picasso. But there are also many Mexico artists represented, including Diego Riviera. There's even an extensive coin collection. Each floor of the museum has a different layout, and you walk along curving ramps (not unlike those in the Guggenheim Museum in New York City) to get from one floor to another. Interestingly,
some paintings are hung so that they can be viewed from both front and back. Designed by the Mexican architect Fernando Romero, Slim's son-in-law, the $70 million building has a shape some have likened to a silver cloud, and is covered by thousands of hexagonal aluminum tiles. The museum is most easily reached by taxi.
