Museo Soumaya

From outside, the Museo Soumaya in Mexico City looks like a silver tornado frozen mid-turn, a windowless tower wrapped in some 16,000 hexagonal mirrored tiles that shift colour with the sky. It was designed by the Mexican architect Fernando Romero and opened in 2011, the private museum of Carlos Slim, the telecoms magnate long ranked among the world's richest people, named for his late wife Soumaya.

Inside, a spiralling ramp climbs past a collection of nearly 70,000 objects. Slim bought on a huge scale, and the top floor holds one of the largest collections of Auguste Rodin's sculpture outside France, casts of The Thinker and The Kiss among them, along with Dalí and European painting from Old Masters to the Impressionists.

Entry is free to everyone, every day.
