Acuario Inbursa

This guide to Acuario Inbursa in Mexico City opens with a question: why the richest man in a country with two oceans built one more, four stories underground on a traffic triangle in Nuevo Polanco. It follows Carlos Slim's decision to dig down rather than up, the son-in-law architect Fernando Romero he hired, and the roughly nineteen-million-dollar bill for a million and a half liters of trucked-in seawater. Across the street stands the Soumaya, the museum Slim built for his late wife's art collection, and he wanted this corner to hold something alive to match it.
