Polyforum Cultural Siqueiros is a 12-sided cultural venue wrapped inside and out in murals by David Alfaro Siqueiros. Its main work, La Marcha de la Humanidad, is one of the largest mural cycles in the world and turns the building itself into the attraction.
The exterior murals can be appreciated quickly from the street, but the interior is the reason to make a deliberate stop. It pairs well with a Condesa, Roma, or Del Valle day focused on modern architecture, public art, and Mexico City's muralist legacy.
