Polyforum Cultural Siqueiros, Cultural center in Colonia Nápoles, Mexico City.

The Polyforum Cultural Siqueiros is a cultural complex in Mexico City whose exterior takes the form of a diamond, with eight sides inside and a twelve-panel sculptural mural outside. The panels, painted in red, black, white and blue-gray, depict concepts such as The Leadership, The Circus and The Dance. A glass-walled ground floor sits beneath a dark overhang, and two bronze figures stand on the lawn in front.

Patron Manuel Suárez first requested a large mural for Cuernavaca, but Siqueiros officially accepted the commission for the Polyforum on September 7, 1964. The building was designed as part of the Mexico 2000 redevelopment project at Parque de la Lama. In 1970 an exterior wall was added to protect the property; its inner surface celebrates the fiftieth anniversary of the Mexican mural movement.

The building is named after the artist David Alfaro Siqueiros and reflects his belief that art should express human experience and social change. Today, the space hosts exhibitions and performances that engage with artistic and social topics.

The Polyforum stands on Avenida de los Insurgentes beside the World Trade Center complex, between Colonia Nápoles and Colonia Del Valle. The Polyforum Metrobús station is a few metres away. The Foro Universal is entered from the glass-walled ground floor; the rotating central platform, 24 metres across, carries visitors past the mural covering walls and ceiling.

Inside, visitors can experience the main mural from a rotating platform while listening to a recorded voice of the artist explaining the different scenes. This setup creates an immersive experience where the artwork and artistic explanation happen together.
