Museo Soumaya: The Architecture by Fernando Romero

An explanation of Fernando Romero's Museo Soumaya, from its mirrored hexagonal skin to its structural logic.

Museo Soumaya: The Architecture by Fernando Romero

The Museo Soumaya in Mexico City is one of the most photographed buildings in Latin America, a shimmering, twisting form clad in thousands of metal hexagons. Designed by Mexican architect Fernando Romero and completed in 2011, it houses the art collection of the Carlos Slim foundation. Beyond its striking image, the building is an exercise in sculptural form, structural ambition, and urban presence.

A sculptural form in the city

The museum sits in the Plaza Carso development in the Polanco area, and it was conceived as an object to be seen in the round. Its silhouette is often described as an anvil or an hourglass, narrowing at the middle and flaring at top and base. There is no obvious front or back. The curving, asymmetrical mass rotates as you move around it, which makes the building behave more like a sculpture than a conventional facade-driven structure.

The hexagonal skin

The most recognizable feature is the envelope, made of roughly 16,000 mirror-polished aluminum hexagonal tiles. The hexagon allows the cladding to wrap a doubly curved surface smoothly, since the modules can tilt and follow the complex geometry. The reflective surface shifts with the sky and light through the day, so the building never looks quite the same twice. It is a clear example of how a single repeated module can clothe an irregular form.

Structure and interior

Behind the skin, the building relies on a structure of curved steel columns and ring beams that give it its twisting profile without interior columns interrupting the galleries. The exhibition spaces spiral upward and culminate in a top-lit gallery often used for the museum's Rodin sculptures, where natural light filters through the roof. The journey through the floors is processional, ending in the brightest and most open room.

Reactions and significance

The Museo Soumaya has drawn both admiration and criticism. Supporters praise its boldness and the way it gave Mexico City an instantly iconic cultural landmark. Critics question how well the curving galleries serve the art and whether the form prioritizes image over function. Both readings are part of why the building matters: it forced a public conversation about ambition, spectacle, and the role of the icon in contemporary museum design.

Why it belongs in any study of Mexican architecture

For anyone studying recent Mexican architecture, the Soumaya is a key reference. It represents a moment when Mexico City asserted itself on the global stage with a building meant to compete with the world's signature museums. Studios working in Mexico today, including practices like MÉTODO Arquitectos, operate in a context that buildings like this helped define, where formal ambition and international visibility became part of the conversation.

Closing

The Museo Soumaya by Fernando Romero is best understood as a sculptural icon wrapped in a hexagonal mirror skin, supported by an ambitious steel structure. Whether read as triumph or provocation, it remains one of the defining works of twenty-first-century Mexican architecture and a landmark that reshaped its corner of Mexico City.
