Defined by its mushroomlike form and its skin of locally sourced hexagonal aluminum tiles, the Museo Soumaya is located in the Plaza Carso—developed by billionaire Carlos Slim and largely designed by his son-in-law, architect Fernando Romero.
The museums second-floor lobby is column-free, save for one slanted support that cuts into the gallery above.
On the upper floors, many of the artworks are shown either in display cases or on stands situated among crafted circulation paths.
Since art cannot be hung off of the curving, elastomeric-coated interior walls, paintings are hung on freestanding partitions.
A curving ramp leads from the seventh floor to the cavernous eighth-floor gallery. A venue for showcasing Slim's large collection of Rodin and Dalí sculptures, the gallery is the only publicly accessible space in the museum with natural daylight, which filters in through a skylight.
