"The Museo Soumaya, financed by Carlos Slim, the richest man in Mexico , has the ambitions of the Guggenheim Bilbao from the outside. It's a stunning building whose sweeping, soaring curves couldn't help but make it an instant landmark near Polanco, one of Mexico City 's ritziest neighborhoods. Inside, the museum recalls the Guggenheim New York, with galleries off of a ramp which spirals down (or up) the building. Unfortunately the museum's permanent collection isn't as impressive as those at either Guggenheim. The Soumaya does have some strengths—one of the world's largest collection of Rodins and some especially noteworthy colonial Mexican works—but it can feel hit or miss, with many undistinguished pieces. Slim's museum is free, however, so you won't regret paying admission even if you just pass through quickly to take in the building itself and some highlights."
